Function
I/O circuit
System reset input.
In CPU operating mode or halt mode, applications must apply a low level for at least
one full machine cycle to reset the system and restart execution with the PC set to
location 0. This pin is connected in parallel with the internal power on reset circuit.
53
RES
I
Tuning voltage generation circuit outputs.
These pins include an n-channel transistor, and a tuning voltage can be generated by
connecting external coil, diode, and capacitor components.
FM DC-DC clock switching is a mask option.
54
TU
O
N-channel open-drain
FM VCO (local oscillator) input.
This pin is selected with the PLL instruction CW1.
The input must be capacitor coupled.
Input is disabled in backup mode, in halt mode, after a reset, and in PLL stop mode.
56
FMIN
I
CMOS amplifier input
AM VCO (local oscillator) input.
This pin and the bandwidth are selected with the PLL instruction CW1.
The input must be capacitor coupled.
Input is disabled in backup mode, in halt mode, after a reset, and in PLL stop mode.
57
AMIN
I
CMOS amplifier input
Main charge pump output. When the local oscillator frequency divided by N is higher
than the reference frequency a high level is output, when lower, a low level is output.
The pin is set to the high-impedance state when the frequencies match.
Output goes to the high-impedance state in backup mode, in halt mode, after a reset,
and in PLL stop mode.
59
EO
O
Transistor used for the low-pass filter amplifier.
Connect AGND to ground.

Note 2:
When a pin in an I/O switching port is used as an output, applications must first set up the data with an OUT, SPB, or RPB instruction and then set
up output mode with an IOS instruction.
