 PIN STATUS IN EACH CPU STATE

The terms used for pin status have the following meanings.

・INITX=0

This is the period when the INITX pin is the "L" level.

・INITX=1

This is the period when the INITX pin is the "H" level.

・SPL=0

This is the status that standby pin level setting bit (SPL) in standby mode control register (STB_CTL) is

set to "0".

・SPL=1

This is the status that standby pin level setting bit (SPL) in standby mode control register (STB_CTL) is

set to "1".

・Input enabled

Indicates that the input function can be used.

・Internal input fixed at "0"

This is the status that the input function cannot be used. Internal input is fixed at "L".

・Hi-Z

Indicates that the output drive transistor is disabled and the pin is put in the Hi-Z state.

・Setting disabled

Indicates that the setting is disabled.

・Maintain previous state

Maintains the state that was immediately prior to entering the current mode.

If a built-in peripheral function is operating, the output follows the peripheral function.

If the pin is being used as a port, that output is maintained.

・Analog input is enabled

Indicates that the analog input is enabled.

・Trace output

Indicates that the trace function can be used.
