 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 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.
