Bit 7 – IWUPB Intermittent WUP Mode Path B

If this bit is set to ‘1’, path B is restarted when an end of telegram (EOT) is detected while waiting for a wait check OK (WCO). Wake check OK time-out remains untouched and continues to run. If this bit is cleared, receiving an EOT while waiting for WCO is considered an error and the get telegram state machine is either stopped or the path B is restarted, depending on the DARB setting. Wake check OK time-out is restarted too.

Bit 6 – DARB Demodulator Automatic Restart on Path B

If this bit is set to ‘1’, do an automatic restart of demodulator path B if an EOTB has occurred while waiting for WCOB or SOTB. If this bit is set to ‘0’, reception is stopped after an EOTB or time-out has occurred on path B and the state machine path B stops its operation.

Bit 5 – GAPMB Gap Mode Path B

If this bit is set to ‘1’, path B is restarted when an end of telegram (EOTB) is detected while waiting for a start of telegram (SOTB). The SOT time-out remains untouched and continues to run. If this bit is cleared, receiving an EOTB while waiting for SOTB is considered an error and the get telegram state machine is either stopped or the path B is restarted, depending on the DARB setting. All time-outs are restarted too.

Bit 4 – RXTEHB RX Telegram End Handling Path B

This bit selects the behavior of the state machine after successfully receiving an end of telegram.

0 = stop immediate

1 = restart RX after EOT

Bit 3 – IWUPA Intermittent WUP Mode Path A

If this bit is set to ‘1’, path A is restarted when an end of telegram (EOT) is detected while waiting for a wait check OK (WCO). Wake check OK time-out remains untouched and continues to run. If this bit is cleared, receiving an EOT while waiting for WCO is considered an error and the get telegram state machine is either stopped or path A is restarted, depending on the DARA setting. Wake check OK time-out is restarted too.

Bit 2 – DARA Demodulator Automatic Restart on Path A

If this bit is set to ‘1’, do an automatic restart of demodulator path A if an EOTA has occurred while waiting for WCOA or SOTA. If this bit is set to ‘0’, reception is stopped after an EOTA or time-out has occurred on path A and the state machine path A stops its operation.

Bit 1 – GAPMA Gap Mode Path A

If this bit is set to ‘1’, path A is restarted when an end of telegram (EOTA) is detected while waiting for a start of telegram (SOTA). The SOT time-out remains untouched and continues to run. If this bit is cleared, receiving an EOTA while waiting for SOTA is considered an error and the get telegram state machine is either stopped or the path A is restarted completely depending on DARA setting. All time-outs are restarted too.

Bit 0 – RXTEHA RX Telegram End Handling Path A

This bit selects the behavior of the state machine after the successful reception of an end of telegram.

0 = Stop immediate

1 = Restart RX after EOT
