This is the PLL charge pump output pin.
When the frequency of the local oscillation
signal frequency is divided by N is higher than
the reference frequency, a high level signal is
output from the PD1 pin. When the frequency
is lower, a low level signal is output. If the
frequencies match, the pin goes to high
impedance.
A high-speed lockup circuit can be formed by
using this pin in combination with the main
charge pump.
For details, refer to page that describes the
charge pump configuration.
Serial data: HCTR is selected if CTS1 = 1 is
set.
The input frequency is 0.4 to 25 MHz.
The signal is passed through to the general-
purpose counter internally, via the 1/2
frequency divider. An integrating count can
also be kept.
The count result is output from the MSB of
the general-purpose counter through the
output pin DO.
For details, refer to page that describes the
general-purpose counter configuration.
Serial data: Prohibited when HCTR = 0.
This is the output buffer for the crystal
oscillator circuit.
Serial data: When XB = 1 is set, the output
buffer operates and the crystal oscillator
signal (pulse) is output.
When XB = 0, this pin outputs a low level.
(When a power-on reset is executed, XB = 0
and the output buffer is fixed at the low level.)
