■ PIN STATUS IN EACH CPU STATE

• When INIT = “L”

This is the period when the INIT pin is the “L” level.

• When INIT = “H”

The status immediately after the INIT pin changes from the “L” level to the “H” level.

•SLVL1

This bit is a standby level setting bit in the standby mode control register (STBCR) .

• Input enabled

Indicates that the input function can be used.

• Input disabled

Indicates that the input function cannot be used.

• Output Hi-Z

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

• Maintain previous state

Maintains the state that was being output 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.

• Internal input fixed at “0”

The input gate connected to the pin is disconnected from the external input and internally connected to “0”.

• Input enabled when interrupt function selected and enabled

Inputs are allowed only when the pin is configured as an external interrupt request input pin and the external

interrupt request is enabled.
