(3) Description of registers
(a) Serial-mode register 1 (SMR1)
The SMR1 is used to control serial I/O.
[Bit 7] SIOF: Serial I/O interrupt-request flag
Bit 7 indicates the serial I/O transfer state.
The meaning of each bit to be read is as follows:
Note that 1 is always read when the Read Modify Write instruction is read. If this bit is set when an inter-
rupt is enabled (SIOE = 1), an interrupt request is output to the CPU.
The meaning of each bit to be written is as follows:
The end-of-transfer decision may be made by either the SST bit (bit 0) of the SMR or by this bit.
[Bit 6] SIOE: Serial I/O interrupt-enable bit
Bit 6 is used to enable a serial I/O interrupt request.
[Bit 5] SCKE: Shift-clock output-enable bit
Bit 5 is used to control the shift-clock I/O pins.
When using the P33/SCK1 and P55/SCK2 pins as external clocks, always set the DDR to input (bit 3 of
DDR3 = 0).
