Dedicated output port
Since these pins are high breakdown voltage n-channel
transistor open-drain outputs, they can be effectively used for
functions such as band power supply switching.
Note that PH1 is also used as the BEEP output and that PH2
and PH3 are also used as the DAC1 and DAC2 outputs.
These ports go to the high impedance state during a reset,
i.e., when the RES pin is low, and in BACKUP mode.
Dedicated output port
While these pins have a CMOS output circuit structure, they
can be switched to function as LCD drivers. Their function is
switched by the SS and RS instructions. These pins cannot
be switched individually.
The LCD driver function is selected and a segment off signal
is output when power is first applied or when RES is low.
These pins are held at the low level in BACKUP mode.
Note that when the general-purpose port use option is
specified, these pins output the contents of IPORT when LPC
is 1, and the contents of the general-purpose output port
LATCH when LPC is 0.
LCD driver segment outputs
A frame frequency of 100 Hz and a 1/2 duty, 1/2 bias drive
type are used.
A segment off signal is output when power is first applied or
when RES is low.
These pins are held at the low level in BACKUP mode.
The use of these pins as general-purpose output ports can be
specified as an option.
LCD driver common outputs
A 1/2 duty, 1/2 bias drive type is used.
The output when power is first applied or when RES is low is
identical to the normal operating mode output.
These pins are held at the low level in BACKUP mode.
FM VCO (local oscillator) input
The input must be capacitor-coupled.
The input frequency range is from 10 to 130 MHz.
AM VCO (local oscillator) input
The band supported by this pin can be selected using the PLL
instruction.
