This register selects the validation criteria to be used in determining a valid bit
oriented code (BOC) and enables generation of an interrupt on a change in code
status of the BOC received on RXDn+/-.
IDLE:
The IDLE bit enables the assertion of the INTB output when there is a
transition from a validated BOC to idle code. When IDLE and the Master
Interrupt Enable bit of the Master Configuration register are set to logic 1, the
interrupt is enabled.
AVC:
The AVC bit position selects the validation criteria used in determining a valid
BOC. A logic 1 in the AVC bit position selects an alternate validation criterion
of 4 out of 5 matching BOCs; a logic 0 selects the 8 out of 10 matching BOC
criterion. Unless fast declaration is necessary, it is recommended that AVC
be set to logic 0 to improve bit error tolerance.
BOCE:
The BOCE bit enables the assertion of the INTB output when a valid BOC is
detected. When BOCE and the Master Interrupt Enable bit of the Master
Configuration register are set to logic 1, the interrupt is enabled.
