UART2 Special Mode Register
Figure 1.16.28. Some other functions added
Some other functions added are explained here. Figure 1.16.28 shows their workings.
Bit 4 of the UART2 special mode register is used as the bus collision detect sampling clock select bit. The
bus collision detect interrupt occurs when the R
mity is detected in synchronization with the rising edge of the transfer clock signal if the bit is set to “0”. If
this bit is set to “1”, the nonconformity is detected at the timing of the overflow of timer A0 rather than at
the rising edge of the transfer clock.
Bit 5 of the UART2 special mode register is used as the auto clear function select bit of transmit enable
bit. Setting this bit to “1” automatically resets the transmit enable bit to “0” when “1” is set in the bus
collision detect interrupt request bit (nonconformity).
Bit 6 of the UART2 special mode register is used as the transmit start condition select bit. Setting this bit
to “1” starts the TxD transmission in synchronization with the falling edge of the RxD terminal.
