PMR2 is an 8-bit read/write register for controlling the selection of pin functions for pins P2

0 to

3 and P27, controlling the PMOS on/off option for pin P23/SO1, and controlling the TMIG input

noise canceller.

Upon reset, PMR2 is initialized to H'40.

Bits 7—P2

7/IRQ0 Pin Function Switch (IRQ0): This bit selects whether pin P27/IRQ0 is used as

7 or as IRQ0.

Bit 7: IRQ0

Description

Functions as P2

7 input pin

(initial value)

Functions as

IRQ

0 input pin

Bit 6—Reserved Bit: Bit 6 is reserved: it is always read as 1, and cannot be modified.

Bit 5—P2

3/SO1 pin PMOS control (POF1): This bit turns on and off the PMOS transistor in the

3/SO1 pin output buffer.

Bit 5: POF1

Description

CMOS output

(initial value)

NMOS open-drain output

Bit 4—TMIG noise canceller select (NCS): This bit controls the noise canceller circuit for input

capture at pin TMIG.

Bit 4: NCS

Description

Noise canceller function not selected

(initial value)

Noise canceller function selected
