Initial setting:
Specify the receive data format.
Start reception:
When SSRDR is dummy-read with RE = 1, reception is
started.
When a receive error occurs, execute the designated error
processing after reading the ORER bit in SSSR. After that,
clear the ORER bit to 0. While the ORER bit is set to 1,
transmission or reception is not resumed.
To continue single reception:
When continuing single reception, wait for time of t
while the RDRF flag is set to 1 and then read receive data
in SSRDR.
The next single reception starts after reading receive data
in SSRDR.
To complete reception:
To complete reception, read receive data after clearing the
RE bit to 0. When reading SSRDR without clearing the RE
bit, reception is resumed.
