STS wait state: The serial interface enters STS wait state by MCU reset (00, 10 in figure 71). In STS
wait state, the serial interface is initialized and the transmit clock is ignored. If the STS instruction is
then executed (01, 11), the serial interface enters transmit clock wait state.
Transmit clock wait state: Transmit clock wait state is between the STS execution and the falling edge
of the first transmit clock. In transmit clock wait state, input of the transmit clock (02, 12) increments
the octal counter, shifts the serial data register, and enters the serial interface in transfer state. However,
note that if continuous clock output mode is selected in internal clock mode, the serial interface does not
enter transfer state but enters continuous clock output state (17).
The serial interface enters STS wait state by writing data to serial mode register A (SMRA: $005) (04,
14) in transmit clock wait state.
Transfer state: Transfer state is between the falling edge of the first clock and the rising edge of the
eighth clock. In transfer state, the input of eight clocks or the execution of the STS instruction sets the
octal counter to 000, and the serial interface enters another state. When the STS instruction is executed
(05, 15), transmit clock wait state is entered. When eight clocks are input, transmit clock wait state is
entered (03) in external clock mode, and STS wait state is entered (13) in internal clock mode. In
internal clock mode, the transmit clock stops after outputting eight clocks.
In transfer state, writing data to serial mode register A (SMRA: $005) (06, 16) initializes the serial
interface, and STS wait state is entered.
If the state changes from transfer to another state, the serial interrupt request flag (IFS: $023, bit 2) is set
by the octal counter that is reset to 000.
Continuous clock output state (only in internal clock mode): Continuous clock output state is entered
only in internal clock mode. In this state, the serial interface does not transmit/
receive data but only outputs the transmit clock from the
SCK
pin.
When bits 1 and 0 (PMRA1, PMRA0) of port mode register A (PMRA: $004) are 00 in transmit clock
wait state and if the transmit clock is input (17), the serial interface enters continuous clock output state.
If serial mode register A (SMRA: $005) is written to in continuous clock output mode (18), STS wait
state is entered.
