R/W Description
R/W Transfer Mode
R/W Selects transfer mode.
00: Slave mode 1
01: Slave mode 2
10: Master mode 1
11: Master mode 2
Note: For the operation in each mode, see section 17.4.3,
Transfer Data Format.
R
Reserved
This bit is always read as 0. The write value should always
be 0.
R/W Receive Data Sampling Edge
The TXD_SIO signal is transmitted at the opposite edge
where the RXD_SIO signal is sampled (see figure 17.4).
0: RXD_SIO is sampled at the falling edge of SCK_SIO
1: RXD_SIO is sampled at the rising edge of SCK_SIO
Note: This bit is valid in master mode 1 and master mode 2.
