Bits 7, 6, 5, and 3: Reserved Bits: Bits 7, 6, 5, and 3 are reserved bits. They are always read

as 1 and cannot be modified.

Bit 4—Reserved Bit: Bit 4 is reserved: it should be used set to 1.

Bit 2—P2

6/TXD Pin Function Switch (TXD): This bits selects whether the P26/TXD pin is

used as P2

6 or as TXD.

Bit 2: TXD

Description

Functions as P2

6 I/O pin

(initial value)

Functions as TXD output pin

Bits 1 and 0—Reserved Bits: Bits 1 and 0 are reserved: they should be used cleared to 0.

Port Pull-Up Control Register 2 (PUCR2)

Bit

76543210

PUCR2

Initial value

00000000

Read/Write

R/W

PUCR2 controls whether the MOS pull-up of each port 2 pin is on or off. When a PCR2 bit is

cleared to 0, setting the corresponding PUCR2 bit to 1 turns on the MOS pull-up for the

corresponding pin, while clearing the bit to 0 turns off the MOS pull-up.

Upon reset, PUCR2 is initialized to H'00.

Note:

As P2

7 is an input-only pin, the MOS pull-up is turned off regardless of whether PUCR27

is set to 1 or cleared to 0.
