Figure 59 Serial Interface State Transitions
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 1 (SR1L: $006, SR1U: $007), 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 1A (SM1A: $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 1A (SM1A: $005) (06, 16) initializes the serial
interface, and STS wait state is entered.
