Figure 56 Serial Mode Register 1 (SMR1)
Serial mode register 2 (SMR2: $025):
Serial mode register 2 (SMR2) has the following functions. See figure 57.
R2
2
/SI/SO pin PMOS control
Idle high/low control
Serial mode register 2 (SMR2) is a 2-bit write-only register. The register value cannot be modified in the
transfer state.
Bit 2 (SMR22) of serial mode register 2 (SMR2) controls the on/off status of the R2
2
/SI/SO pin PMOS.
The bit 2 (SMR22) only is reset to 0 by an MCU reset.
