Description

Clock innput/output for serial I/O5. This function is enabled when serial I/O5 is

using the external shift clock mode, or serial I/O5 clock output function is en-

abled.

D

General purpose input/output port. This function is enabled when serial I/O5 is

not using the external shift clock mode with the serial I/O5 clock output function

disabled.

H NMI (Non Maskable Interrupt) input

B Output clock cycle time. Sub clock

B Input clock cycle time. Sub clock

2 to 0Mode Pins. The levels applied to these pins set the basic operating mode.

Connect VCC or VSS.

H, J Input circuit configuration:

The production model (masked-ROM model) is type “H”.

The Flash ROM model is type “J”.

A Input clock cycle time. Main clock

A Output clock cycle time. Main clock

I External reset input

External input for DMA transfer requests. Since this input is used as required

when selected as a DMA start source, the port output must remain off unless in-

C tentionally turned on.

General purpose input/output port.

External acknowledge output for DMA transfer requests. This function is enabled

when the transfer request acceptance output for DMA is enabled.

C

General purpose input/output port. This function is enabled when the transfer re-

quest acceptance output for DMA is enabled.

Completion output for DMA external transfer. This function is enabled when the

external transfer end output for DMA is enabled.

C

Stop input for DMA external transfer. This function is enabled when the external

transfer stop input for DMA is enabled.

General purpose input/output port. This function is enabled when the external

transfer end output and external transfer stop input for DMA are disabled.

External input for DMA transfer requests. Since this input is used as required

when selected as a DMA start source, the port output must remain off unless in-

C tentionally turned on.

General purpose input/output port.

External acknowledge output for DMA transfer requests. This function is enabled

when the transfer request acceptance output for DMA is enabled.

C

General purpose input/output port. This function is enabled when the transfer re-

quest acceptance output for DMA is disabled.
