11. 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 at the L level.

INITX = 1

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

SPL = 0

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

(STB_CTL) is set to 0.

SPL = 1

This is the status that the standby pin level setting bit (SPL) in the 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 pin 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.

GPIO selected

In Deep standby mode, pins switch to the general-purpose I/O port.

Setting prohibition

Prohibition of a setting by specification limitation
