PE0 also has a continuous pulse (64·Tcyc) output
function.
PE1 becomes the watchdog reset pin WDR when
selected for such as an option.
(1) Open-drain output
(2) Pull-up resistor
Options (1) and (2) can be
specified in bit units
(3) Normal port PE1
(4) Watchdog reset WDR
Either options (3) and (4)
may be specified.

I/O
I/O port F0 to F3
The port functions and options are identical to
those of PE0 to PE1 (See note.)
PF0 to PF3 have shared functions as the serial
interface pins and the INT input.
The function can be selected under program
control.
SI ... Serial input pin
SO ... Serial output pin
SCK ... Input and output of the serial clock signal
INT ... Interrupt request input
The serial I/O function can be switched between 4-
bit and 8-bit transfers under program control.
Note: There is no continuous pulse output function.
