P12 Operation Mode Register (P12MOD)

<Address: H’0080 074C>

Bit Name

Function

0–3

No function assigned. Fix to "0."

P124MD

0: P124/DD3 (Note 1)

Port P124 operation mode bit (Note 3)

1: TCLK0/A9 (Note 2)

P125MD

0: P125/DD2 (Note 1)

Port P125 operation mode bit (Note 3)

1: TCLK1/A10 (Note 2)

P126MD

0: P126/DD1 (Note 1)

Port P126 operation mode bit

1: TCLK2/CS2# (Note 2)

P127MD

0: P127/DD0 (Note 1)

Port P127 operation mode bit

1: TCLK3/CS3# (Note 2)

Note 1: The DD input functions are effective depending on the settings of DD input pin select register (DDSEL). (For details, refer to

the Chapter 14, "Direct RAM Interface") 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 P12 Peripheral Function Select Register is set.

Note 3: During processor mode, settings of this bit have no effect and the port functions as external bus interface signal pin (A9 or A10).

P12 Peripheral Function Select Register (P12SMOD)

<Address: H’0080 076C>

Bit Name

Function

0–3

No function assigned. Fix to "0."

P124SMD

0: TCLK0

Port P124 peripheral function select bit (Note 1)

1: A9

P125SMD

0: TCLK1

Port P125 peripheral function select bit (Note 1)

1: A10

P126SMD

0: TCLK2

Port P126 peripheral function select bit

1: CS2#

P127SMD

0: TCLK3

Port P127 peripheral function select bit

1: CS3#

Note 1: During processor mode, settings of this bit have no effect and the port functions as external bus interface signal pin (A9 or A10).

Note: • The value of this register can only be modified when the corresponding P12 operation mode register bit = 0 (set for port). Then

set the corresponging P12 operation mode register bit to "1."
