P3 Operation Mode Register (P3MOD)

<Address: H’0080 0743>

Bit Name

Function

P30MD

0: P30/DD16 (Note 1)

Port P30 operation mode bit

1: A15/TIN4 (Note 2)

P31MD

0: P31/DD17 (Note 1)

Port P31 operation mode bit

1: A16/TIN5 (Note 2)

P32MD

0: P32/DD18 (Note 1)

Port P32 operation mode bit

1: A17/TIN6 (Note 2)

P33MD

0: P33/DD19 (Note 1)

Port P33 operation mode bit

1:A18/TIN17 (Note 2)

P34MD

0: P34/DD20 (Note 1)

Port P34 operation mode bit

1:A19/TIN30 (Note 2)

P35MD

0: P35/DD21 (Note 1)

Port P35 operation mode bit

1:A20/TIN31 (Note 2)

P36MD

0: P36/DD22 (Note 1)

Port P36 operation mode bit

1: A21/TIN32 (Note 2)

P37MD

0: P37/DD23 (Note 1)

Port P37 operation mode bit

1: A22/TIN33 (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 P3 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 (A15-A22).

1: TIN30

P35SMD

0: A20

Port P35 peripheral function select bit

1: TIN31

P36SMD

0: A21

Port P36 peripheral function select bit

1: TIN32

P37SMD

0: A22

Port P37 peripheral function select bit

1: TIN33

Notes: • During processor mode, settings of this bit have no effect and the ports function as external bus interface signal pins (A15-A22).

• The value of this register can only be modified when the corresponding P3 operation mode register bit = 0 (set for port).

Then set the corresponging P3 operation mode register bit to "1."

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