Output
Output-only port.
Since these ports are high-voltage handling n-channel
transistor open-drain outputs, they are effective for use
in band power supply switching. Note that PH1, PH2,
and PH3 have shared functions as the BEEP

This port goes to the
high-impedance state in backup mode and after a reset
(when the RES pin is set low).

Output
Output-only port.
These pins are CMOS outputs, but can be switched to
function as LCD driver outputs. The SS and RS
instructions are used to switch the port function. The
port function cannot be switched in single pin units.
The LCD driver function is selected and a display off
signal is output when RES is low and when power is
first applied. In backup mode the output is held at the
low level.
Note that when use as a general-purpose port is
specified as an option, the contents of IPORT are
output when LPC is 1, and the contents of the general-
purpose output port latch is are output when LPC is 0.
S1 to S24
63 to 40
Output
LCD driver segment outputs.
The fame frequency is 100 Hz.
The drive type is 1/2-duty 1/2-bias drive.
A display off signal is output when RES is low and when
power is first applied.
In backup mode the outputs are held at the low level.
An option is available that allows these pins to be used
as general-purpose outputs.

Output
LCD driver common outputs.
The drive type is 1/2-duty 1/2-bias drive.
These pins output the same signal as is output during
normal operation when RES is low and when power is
first applied.
In backup mode these outputs are held at the low level.
FM IN

Input
FM VCO (local oscillator) input.
Input must be supplied through a coupling capacitor.
The input frequency range is 10 to 130 MHz.
AM IN

AM VCO (local oscillator) input.
Input must be supplied through a coupling capacitor.
The pin frequency band can be selected with the PLL
instruction CW1 bit.
