1. When an external clock is selected, the conditions must be met while if the CKPOL bit in the UiC0 register is set to “0”
2. If an overrun error occurs, bits 8 to 0 in UiRB register are undefined. The IR bit in the SiRIC register remains unchanged.
3. The U0IRS and U1IRS bits respectively are the bits 0 and 1 in the UCON register; the U2IRS bit is bit 4 in the U2C1 register.
The clock synchronous serial I/O mode uses a transfer clock to transmit and receive data. Table 14.1
lists the specifications of the clock synchronous serial I/O mode. Table 14.2 lists the registers used in
clock synchronous serial I/O mode and the register values set.

(transmit data output at the falling edge and the receive data taken in at the rising edge of the transfer clock), the external
clock is in the high state; if the CKPOL bit in the UiC0 register is set to “1” (transmit data output at the rising edge and the
receive data taken in at the falling edge of the transfer clock), the external clock is in the low state.

This error occurs if the serial I/O started receiving the next data before reading the
UiRB register and received the 7th bit in the the next data
