Pin Status In The Sleep, Stop, Hold, Reset, And Hardware Standby Modes - Fujitsu F2MC-16LX Hardware Manual

5.4.5 Pin status in the Sleep, Stop, Hold, Reset, and Hardware
Standby Modes
Table 5.4-2 lists the status of each pin in the single chip mode. Table 5.4-3 lists the
status of each pin in the external bus 16-bit data bus mode. Table 5.4-4 lists the status
of each pin in the external bus 8-bit data bus mode.

"Input enabled" means that the input function is available. The pull-up or pull-down option or external
*1
input is required. When the pin is used as an output port, the status is the same as other ports.
"Status before the mode retained" means that the status output immediately before the mode is output
*2
as is or input is enabled. Outputting the status output immediately before the mode as is means that
output is performed according to the internal peripheral with output when it is operating or output as a
port is retained.
"Input disabled" means that operation of the input gate that is closest to the pin is enabled, but the
*3
input from the pin cannot internally be accepted because the internal circuit does not operate.
*4
In input interrupted status, input is masked, and "L" level transmitted internally.
"Output Hi-Z" means that the pin driving transistor is placed in the drive prohibited state to set the pin
*5
to high impedance.
The pull-up option is disconnected from each port pin in the stop or hardware standby mode.

Note:
In the stop and hardware standby modes, up to eight external signals can be input and the frequency
of each signal must be 1 kHz or less.
