In this mode, one bit in the IEBus is approximated with one byte of UART mode waveform.
Table 14.17 lists the registers used in IEBus mode and the register values set. Figure 14.30 shows the
functions of bus collision detect function related bits.
If the TxD2 pin output level and RxD2 pin input level do not match, a UART2 bus collision detect interrupt
request is generated.
