Bit name
The P37/BZ/RCO pin serves as a general-purpose port pin (P37)
when this bit is "0"; it serves as the remote-control transmission
frequency output pin (RCO) when the bit is "1". Note that the
buzzer output pin (BZ) setting overrides the setting of this bit.
Writing "0" to this bit clears the counter and stops operation;
writing "1" to the bit restarts counting.

0 Disables output and clears counter.
1 Enables output and starts counting.
To use as the RCO pin, write "00
(BZCR) to disable buzzer output.
The read value is indeterminate.
Writing to this bit has no effect on the operation.
