Figure 53 Serial Mode Register 1A (SM1A)
Serial Mode Register 1B (SM1B: $028):
This register has the following functions (figure 54).
Serial interface 1 prescaler division ratio selection
Serial interface 1 output level control in idle states
Serial mode register 1B (SM1B: $028) is a 2-bit write-only register. It cannot be written during data
transfer.
By setting bit 0 (SM1B0) of this register, the serial interface 1 prescaler division ratio is selected. Only bit
0 (SM1B0) can be reset to 0 by MCU reset. By setting bit 1 (SM1B1), the output level of the SO
1
pin is
controlled in idle states of serial interface 1. The output level changes at the same time that SM1B1 is
written to.
