1. Not all bits in the registers are described above. Set those bits to “0” when writing to the registers in
In this mode, one bit of IE Bus is approximated with one byte of UART mode waveform.
Table 13.1.5.1 lists the registers used in IE Bus mode and the register values set. Figure 13.1.5.1 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.
