Figure 15.31 Bus Collision Detect Function-Related Bits
NOTES:
(1) The ABSCS bit in UiSMR register (bus collision detect sampling clock select)
(2) The ACSE bit in UiSMR register (auto clear of transmit enable bit)
(3) The SSS bit in UiSMR register (transmit start condition select)
i = 0 to 2
This diagram applies to the case where IOPOL bit =1 (reversed).

1.The falling edge of RXDi when IOPOL bit = 0; the rising edge of RXDi when IOPOL bit = 1.
2.The transmit condition must be met before the falling edge
Apr 14, 2006
If SSS bit = 0, the serial interface starts transmitting data one transfer clock cycle after the transmission enable condition is met
If SSS bit = 1, the serial interface starts transmitting data at the rising edge
Transmission enable condition is met

timer Aj: timer A3 when UART0; timer A4 when UART1; timer A0 when UART2
(NOTE 2)
If ABSCS bit = 0, bus collision is determined at the rising edge of the transfer clock

If the ACSE bit = 1 (automatically
clear when bus collision occurs),
the TE bit is set to 0
(transmission disabled) when
the IR bit in the UiBCNIC register = 1
(unmatching detected).
