7.8.3 Pin Functions

Table 7-24 shows the port 9 pin functions.

Table 7-24 Port 9 Pin Functions

Pin Functions and Selection Method

P97/UD

Functions are switched as follows by means of the UP/DOWN bit* in PMR2

and bit PCR97 in PCR9.

UP/DOWN

PCR97

—

Pin function

P97 input pin P97 output pin

UD input pin

Note: * Before entering power-down mode, if this pin is set to UD input by the

UP/DOWN bit in PMR2, it should be kept from floating by external

connection or should be set to general I/O use by clearing the

UP/DOWN bit to 0 prior to the state transition.

P96/SO2*

Functions are switched as follows by means of bit SO2 in PMR2 and bit PCR96

in PCR9.

SO2

PCR96

Pin function

P96 input pin P96 output pin

SO2 output pin

Note: * The PMOS buffer transistor of pin P96/SO2 can be enabled or

disabled by the SO2PMOS bit in PMR3. For details see 11.2.5, Port

Mode Register 3 (PMR3).

P95/SI2/

Functions are switched as follows by means of bit SI2 in PMR2,* bit CS in

PMR3, and bit PCR95 in PCR9.

SI2

—

PCR95

—

Pin function

P95 input pin P95 output pin SI2 input pin CS output pin

Note: * Before entering power-down mode, if this pin is set to SI2 input by bit

SI2 in PMR2, it should be kept from floating by external connection or

should be set to general I/O use by clearing bit SI2 to 0 prior to the

state transition.
