12.8.5
Transmission cannot be started when a receive error flag (ORER, PER, or FER) is set to 1, even if
the TDRE flag is cleared to 0. Be sure to clear the receive error flags to 0 before starting
transmission. Note also that receive error flags cannot be cleared to 0 even if the RE bit is cleared
to 0.

1. When using an external clock source for the serial clock, update TDR with the DTC, and then
2. Before reading the receive data register (RDR) with the DTC, select the receive-data-full
12.8.7
1. Set TE = RE = 1 only when external clock SCK is 1.
2. Do not set TE = RE = 1 until at least four Pφ clocks after external clock SCK has changed
3. When receiving, RDRF is 1 when RE is cleared to 0 after 2.5–3.5 Pφ clocks from the rising
12.8.8
When receiving, RDRF is 1 when RE is cleared to 0 after 1.5 Pφ clocks from the rising edge of the
RxD D7 bit SCK output, but copying to RDR is not possible.

after the elapse of five peripheral clocks (Pφ) or more, input a transmit clock. If a transmit
clock is input in the first four Pφ clocks after TDR is written, an error may occur (figure
