8.3.3 Port Operation Mode and Port Peripheral Function Select Registers

P0 Operation Mode Register (P0MOD)

<Address: H’0080 0740>

Bit Name

Function

P00MD

0: P00/DD0 (Note 1)

Port P00 operation mode bit

1: DB0/TO21 (Note 2)

P01MD

0: P01/DD1 (Note 1)

Port P01 operation mode bit

1: DB1/TO22 (Note 2)

P02MD

0: P02/DD2 (Note 1)

Port P02 operation mode bit

1: DB2/TO23 (Note 2)

P03MD

0: P03/DD3 (Note 1)

Port P03 operation mode bit

1: DB3/TO24 (Note 2)

P04MD

0: P04/DD4 (Note 1)

Port P04 operation mode bit

1: DB4/TO25 (Note 2)

P05MD

0: P05/DD5 (Note 1)

Port P05 operation mode bit

1: DB5/TO26 (Note 2)

P06MD

0: P06/DD6 (Note 1)

Port P06 operation mode bit

1: DB6/TO27 (Note 2)

P07MD

0: P07/DD7 (Note 1)

Port P07 operation mode bit

1: DB7/TO28 (Note 2)

Note 1: The port and DD input functions both are effective. To use the port as DD input pin, set the port direction for input.

Note 2: Which function of the pin is used depends on how the P0 Peripheral Function Select Register is set.

Note: • During processor mode, settings of this register have no effect, and the ports function as external bus interface signal pins (DB0-DB7).

1: TO24

P04SMD

0: DB4

Port P04 peripheral function select bit

1: TO25

P05SMD

0: DB5

Port P05 peripheral function select bit

1: TO26

P06SMD

0: DB6

Port P06 peripheral function select bit

1: TO27

P07SMD

0: DB7

Port P07 peripheral function select bit

1: TO28

Notes: • During processor mode, settings of this register have no effect, and the ports function as external bus interface signal pins (DB0-DB7).

• The value of this register can only be modified when the corresponding P0 operation mode register bit = 0 (set for port).

Then set the corresponging P0 operation mode register bit to "1."

• During single-chip mode, selecting the external bus interface function is prohibited.
