mode), BIDE bit = 0 (standard mode) and MSS bit = 0
(operates as slave device)
The SSTRSR register is the shift register to transmit and receive the serial data.
When the transmit data is transferred from the SSTDR register to the SSTRSR register and the MLS bit in the
SSMR register is set to 0 (MSB-first), the bit 0 in the SSTDR register is transferred to the bit 0 in the SSTRSR
register. When the MLS bit is set to 1 (LSB-first), the bit 7 in the SSTDR register is transferred to the bit 0 in the
SSTRSR register.
Connecting association between the data I/O pin and SSTRSR register (SS shift register) changes according to
a combination of the MSS bit in the SSCRH register and the SSUMS bit in the SSMR2 register. Also,
connecting association changes according to the BIDE bit in the SSMR2 register.
Figure 16.11 shows an Association between Data I/O Pins and SSTRSR Register.
