This routine is repeatedly executed while PB1 is pressed, because continuous execution was selected at POR (CA1E code issued in
the power-on reset section before).
RX-TX ALIGNMENT PROCEDURES
RX-TX frequency offset can be caused only by the differences in the actual reference frequency. To minimize these errors it is suggested to
use the same crystal type and the same PCB layout for the crystal placement on the RX and TX PCBs.
To verify the possible RX-TX offset it is suggested to measure the CLK output of both chips with a high level of accuracy. Do not measure the
output at the XTL pin since the measurement process itself will change the reference frequency. Since the carrier frequencies are derived
from the reference frequency, having identical reference frequencies and nominal frequency settings at the TX and RX side there should be
no offset if the CLK signals have identical frequencies.
It is possible to monitor the actual RX-TX offset using the AFC status report included in the status byte of the receiver. By reading out the
status byte from the receiver the actual measured offset frequency will be reported. In order to get accurate values the AFC has to be
disabled during the read by clearing the "en" bit in the AFC Control Command (bit 0).
