S6E1C3 Series
Each pin status
The meaning of the symbols in the pin status table is as follows.
IS Digital output is disabled. (Hi-Z) Pull up register is off. Digital input is shut off by fixed 0.
IE _{Digital output is disabled. (Hi-Z) Pull up register is off. Digital input is not shut off.}
IP ^{Digital output is disabled. (Hi-Z) Pull up register is defined by the value of the PCR register. Digital}
input is not shut off.

Digital output is disabled. (Hi-Z) Pull up register is off. Digital input is shut off in case of the OSC
stop. Digital input is not shut off in case of the OSC operation.
The OSC is in operation state. However, it may be stopped in some operation mode of the CPU.
For detail, see chapter “Low Power Consumption Mode” in peripheral manual.
The OSC is in stop state. (Hi-Z)
USB I/O function is controlled by USB controller.
USB I/O function is disabled(Hi-Z)
Digital output and pull up register is controlled by the register in the GPIO or peripheral function.
Digital input is not shut off
CP ^{Digital output is controlled by the register in the GPIO or peripheral function. Pull up register is off．}
Digital input is not shut off.
HC
Digital output and pull up register is maintained the status that is immediately prior to entering the
current CPU state. Digital input is not shut off
HS
Digital output and pull up register is maintained the status that is immediately prior to entering the
current CPU state. Digital input is shut off
GS
Digital output and pull up register is copied the GPIO status that is immediately prior to entering the
current CPU state and the status is maintained. Digital input is shut off
Additional note
Additional note is described below.
*1
In this type, when internal oscillation function is selected, digital output is disabled. (Hi-Z) pull up
register is off, digital input is shut off by fixed 0.
*2 In this type, when Digital I/O function is selected, internal oscillation function is disabled.
*3
In this type, when analog input function is selected, digital output is disabled, (Hi-Z). pull up register
is off, digital input is shut off by fixed 0.
*4 In this type, when Digital I/O function is selected, analog input function is not available.
*5 In this case, PCR register is initialized to “1”. Pull up register is on.
In this type, when Digital I/O function is selected, USB I/O function is disabled.
*6
This pin does not have pull up register.
*7
In this type, when USB I/O function is selected, digital output is disabled. (Hi-Z), digital input is shut
off by fixed 0.
