The USART module is configured as a Manchester encoder/decoder. Looking at the down-
stream communication channel, Manchester encoded characters are serially sent to the RF
emitter. This may also include a user defined preamble and a start frame delimiter. Mostly, pre-
amble is used in the RF receiver to distinguish between a valid data from a transmitter and
signals due to noise. The Manchester stream is then modulated. See
for an example of ASK modulation scheme. When a logic one is sent to the ASK modulator, the
power amplifier, referred to as PA, is enabled and transmits an RF signal at downstream fre-
quency. When a logic zero is transmitted, the RF signal is turned off. If the FSK modulator is
activated, two different frequencies are used to transmit data. When a logic 1 is sent, the modu-
lator outputs an RF signal at frequency F0 and switches to F1 if the data sent is a 0. See
26-19 on page
From the receiver side, another carrier frequency is used. The RF receiver performs a bit check
operation examining demodulated data stream. If a valid pattern is detected, the receiver
switches to receiving mode. The demodulated stream is sent to the Manchester decoder.
Because of bit checking inside RF IC, the data transferred to the microcontroller is reduced by a
user-defined number of bits. The Manchester preamble length is to be defined in accordance
with the RF IC configuration.
