DESCRIPTION

GP40

Default =0x01

on VTR POR

(R/W)

General Purpose I/0 bit 4.0

Bit[0] In/Out : =1 Input, =0 Output

Bit[1] Polarity : =1 Invert, =0 No Invert

Bit[2] Alternate Function Select

1=DRVDEN0 (Note 4)

0=Basic GPIO function

Bits[6:3] Reserved

Bit[7] Output Type Select

1=Open Drain

0=Push Pull

GP41

Default =0x01

on VTR POR

(R/W)

General Purpose I/0 bit 4.1

Bit[0] In/Out : =1 Input, =0 Output

Bit[1] Polarity : =1 Invert, =0 No Invert

Bit[3:2] Alternate Function Select

11=Reserved

10=Either Edge Triggered Interrupt Input 2 (Note 1)

01=DRVDEN1 (Note 4)

00=Basic GPIO function

Bits[6:4] Reserved

Bit[7] Output Type Select

1=Open Drain

0=Push Pull

GP42

Default =0x01

on VTR POR

(R/W)

General Purpose I/0 bit 4.2

Bit[0] In/Out : =1 Input, =0 Output

Bit[1] Polarity : =1 Invert, =0 No Invert

Bit[2] Alternate Function Select

1=nIO_PME

Note: configuring this pin function as output with non-

inverted polarity will give an active low output signal. The

output type can be either open drain or push-pull.

0=Basic GPIO function

Bits[6:3] Reserved

Bit[7] Output Type Select

1=Open Drain

0=Push Pull
