11. Pin Status in Each CPU State
The terms used for pin status have the following meanings:
ï®INITX = 0
This is the period when the INITX pin is at the L level.
ï®INITX = 1
This is the period when the INITX pin is at the H level.
ï®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.
ï®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.
ï®Input enabled
Indicates that the input function can be used.
ï®Internal input fixed at 0
This is the status that the input function cannot be used. Internal input is fixed at L.
ï® Hi-Z
Indicates that the pin drive transistor is disabled and the pin is put in the Hi-Z state.
ï®Setting disabled
Indicates that the setting is disabled.
ï®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.
ï®Analog input is enabled
Indicates that the analog input is enabled.
ï®Trace output
Indicates that the trace function can be used.
ï®GPIO selected
In Deep standby mode, pins switch to the general-purpose I/O port.
ï®Setting prohibition
Prohibition of a setting by specification limitation
