P7 Operation Mode Register (P7MOD)

<Address: H’0080 0747>

Bit Name

Function

P70MD

0: P70

Port P70 operation mode bit

1: CLKOUT/WR#/BCLK (Note 1)

P71MD

0: P71

Port P71 operation mode bit

1: WAIT# (Note 2)

P72MD

0: P72

Port P72 operation mode bit

1: HREQ#/TIN27 (Note 3)

P73MD

0: P73

Port P73 operation mode bit

1: HACK#/TIN26 (Note 3)

P74MD

0: P74

Port P74 operation mode bit (Note 4)

1: RTDTXD/TXD3 (Note 3)

P75MD

0: P75

Port P75 operation mode bit (Note 4)

1: RTDRXD/RXD3 (Note 3)

P76MD

0: P76

Port P76 operation mode bit (Note 4)

1: RTDACK/CTX1 (Note 3)

P77MD

0: P77

Port P77 operation mode bit (Note 4)

1: RTDCLK/CRX1 (Note 3)

Note 1: These functions are selected using the P7 Peripheral Function Select Register and Bus Mode Control Register.

Note 2: During single-chip mode, settings of this register have no effect, and the port functions as port input/output pin.

Note 3: These functions are selected using the P7 Peripheral Function Select Register.

Note 4: If the NBD function is selected by the NBD Pin Control Register, the port functions as NBD pin no matter how this register is set.

P7 Peripheral Function Select Register (P7SMOD)

<Address: H’0080 0767>

Bit Name

Function

P70SMD

0: CLKOUT/WR# (Note 1)

Port P70 peripheral function select bit

1: BCLK

No function assigned. Fix to "0."

P72SMD

0: HREQ#

Port P72 peripheral function select bit

1: TIN27

P73SMD

0: HACK#

Port P73 peripheral function select bit

1: TIN26

P74SMD (Note 2)

0: RTDTXD

Port P74 peripheral function select bit

1: TXD3

P75SMD (Note 2)

0: RTDRXD

Port P75 peripheral function select bit

1: RXD3

P76SMD (Note 2)

0: RTDACK

Port P76 peripheral function select bit

1: CTX1

P77SMD (Note 2)

0: RTDCLK

Port P77 peripheral function select bit

1: CRX1

Note 1: Which function of the pin is used depends on how the Bus Mode Control Register is set.

Note 2: If the NBD function is selected by the NBD Pin Control Register, the port functions as NBD pin no matter how this register is set.

Note: • The value of this register can only be modified when the corresponding P7 operation mode register bit = 0 (set for port).

Then set the corresponging P7 operation mode register bit to "1."
