Port 6 Register

Bit symbol

−

P65

P64

P63

P60

Read/Write

R/W

After reset

−

(0012H)

Function

(Note)

Always write “1”

(This bit is read as “1”).

Input mode

Note: When port P6 is used in the input mode, P6 register controls the built-in pull-up resistor. Read-modify-write is

prohibited in the input mode or the I/O mode. Setting the built-in pull-up resistor may be depended on the

states of the input pin.

P6FC

(0016H)

Function

0: Port

1: SCLK1

0: Port

1: TXD1

0: Port

1: SCLK0

0: Port

1: TXD0

Note 1:

Read-modify-write instruction is prohibited for P6FC.

Note 2:

To set the TXD pin to open drain, write “1” in bit0 (for TXD0 pin) or bit1 (for TXD1 pin) of the ODE register.

P61/RXD0, P64/RXD1 pins do not have a register changing port/function.

When using as input ports, the serial receive data is input to SIO.
