Table 133. Communication error table
Table 134. Transceive command 1Eh
The Transceive command first executes the Transmit command (see
page
transmitted is sent using the FIFO buffer and all data received is written to the FIFO buffer.
The Transceive command can only be started by the microprocessor.
Remark: To adjust the timing relationship between transmitting and receiving, use the
RxWait register. This register is used to define the time delay between the last bit
transmitted and activation of the receiver. In addition, the BitPhase register determines the
phase-shift between the transmitter and receiver clock.
The status of the transmitter and receiver state machine can be read from bits
ModemState[2:0] in the PrimaryStatus register.
The assignment of ModemState[2:0] to the internal action is shown in
Table 135. Meaning of ModemState
Cause
Received data did not start with the SOF pattern
CRC block is not equal to the expected value
Received data is shorter than the CRC block
The parity bit is not equal to the expected value (i.e. a bit-collision, not parity)
A bit-collision is detected
