PB0

I/O

I/O port B

4-bit CMOS tri-state I/O port. Each bit can be set individually as

either an input or output by PBDIR register. A pull-up resistor for

each bit can be selected individually by PBPLU register.

At reset, the input mode is selected and pull-up resistor is disabled

(high impedance).

SBO0A

Output

Serial interface transmission data out-

put pins

Transmission data output pins for serial interface 0,1,2,4. The out-

put configuration, either COMS push-pull or Nch open-drain can be

selected in P0ODC, P3ODC, P4ODC, P5ODC, P6ODC and

P7ODC registers. Pull-up resistor can be selected in P0PLU,

P3PLU, P4PLU, P5PLU, P6PLU, and P7PLU registers. Select out-

put mode in P0DIR, P3DIR, P4DIR, P5DIR, P6DIR, and P7DIR

registers and set serial data output mode in serial mode register 1

(SC0MD1, SC1MD1, SC2MD1, SC4MD1). These can be used as

normal I/O pins when serial interface is not used.

Input

Serial interface reception data input

pins

Reception data input pins for serial interface 0,1,2,4. Pull-up resis-

tor can be selected in P0PLU, P3PLU, P4PLU, P5PLU, P6PLU

and P7PLU registers. Select the output mode in P0DIR, P3DIR,

P4DIR, P5DIR, P6DIR and P7DIR registers and select serial data

input mode in serial mode register 1 (SC0MD1, SC1MD1,

SC2MD1, SC4MD1). These can be used as normal I/O pins when

serial interface is not used.

I/O

Serial interface Clock I/O pins

Clock I/O pins for serial interface 0,1,2,4. The output configuration,

either COMS push-pull or Nch open-drain can be selected in

P0ODC, P3ODC, P4ODC, P5ODC, P6ODC and P7ODC registers.

Pull-up resistor can be selected in P0PLU, P3PLU, P4PLU,

P5PLU, P6PLU and P7PLU registers. Select clock I/O in P0DIR,

P3DIR, P4DIR, P5DIR, P6DIR and P7DIR registers and serial

mode register 1 (SC0MD1, SC1MD1, SC2MD1, SC4MD1) with the

communication mode. These can be used as normal I/O pins when

serial interface is not used.

TXD0A

Output

UART transmission data output pins

In serial interface 0,1,2 in UART mode, this pin is configured as the

transmission data output pin. The output configuration, either

COMS push-pull or Nch open-drain can be selected in P0ODC,

P4ODC, P5ODC, P6ODC and P7ODC registers. Pull-up resistor

can be selected by P0PLU, P4PLU, P5PLU(D), P6PLU and

P7PLU registers. Select the output mode in P0DIR, P4DIR,

P5DIR, P6DIR and P7DIR registers and select serial data output

mode in serial mode register 1 (SC0MD1, SC1MD1, SC2MD1).

These can be used as normal I/O pins when serial interface is not

used.

RXD0A

Input

UART reception data output pins

In serial interface 0,1,2 in UART mode, this pin is configured as the

reception data input pin. Pull-up resistor can be selected in P0PLU,

P4PLU, P5PLU(D), P6PLU and P7PLU registers. Select the input

mode in P0DIR, P4DIR, P5DIR, P6DIR and P7DIR registers and

select serial input in serial mode register 1 (SC0MD1, SC1MD1,

SC2MD1). These can be used as normal I/O pins when serial

interface is not used.

SDA4A

I/O

IIC data I/O pins

In serial interface 4 in IIC mode, this pin is configured as the data I/

O pin. For the output configuration, select Nch open-drain in

P3ODC and P6ODC register and set pull-up resistor in P3PLU and

P6PLU register. Select the output mode in P0DIR register and

P6DIR register select serial data I/O mode by serial mode register

1 (SC4MD1). These can be used as normal I/O pin when serial

interface is not used.

SDA4B

SCL4A

I/O

IIC clock I/O pins

In serial interface 4 in IIC mode, this pin is configured as the clock

I/O pin. For the output configuration, select Nch open-drain in

P0ODC and P6ODC register and set pull-up resistor by P0PLU

and P6PLU register. Select the output mode at P0DIR register and

P6DIR register select serial clock I/O mode in serial mode register

1 (SC4MD1). These can be used as normal I/O pin when serial

interface is not used
