Status of Pins in Standby Mode and Reset
The statues of pins in standby mode and reset are summarized below for each memory
access mode.
I
Software pull-up resistor
For pins with a pull-up resistor selected by software, the pull-up resistor is disconnected during
“L” level output.
I
Status of pins in single-chip mode
Table 5.7-1 lists the state of pins in single-chip mode.
Table 5.7-1 State of pins in single-chip mode
*1"Input enabled" means that the input function is enabled. Select either the pull-up or the pull-
down option. Alternatively, an external input is required. Pins used as output ports are the
same as other ports.
*2"The preceding status is retained" means that the status of the pin output existing immediately
before switching to this mode is retained. Note that input is disabled if the preceding status
was input.
"Status of the pin output is retained" means that the pin retains the value output from an
operating internal peripheral unit or the value output from the port if the pin is used as a
port.
"Input disabled" means that the input to the pin is not accepted because the internal circuit
is inactive, although operation of the input gate adjacent to the pin is enabled.
*3"Input shut off" indicates the state in which operation of the input gate adjacent to the pin is
disabled. "Output Hi-z" means that the pin state is high-impedance because driving of the
pin driving transistor is disabled.
