eight pulses of the transmit clock, the state changes to the transmit clock wait state for the external clock
mode (03). Also, the state changes to the STS wait state for the internal clock mode (13). In the internal
clock mode, the transmit clock stops after eight pulses of the transmit clock are output.
While in the transfer state, if the serial mode register (SMR: $005) (06, 16) is written to, the serial
interface is initialized and the state changes to the STS wait state.
After the transfer state has changed to another state, the octal counter is reset to 000 and the serial
interrupt request flag (IFS: $003, 2) is set.
Continuous clock output state (internal clock mode only): Continuous clock output state is the state in
which only the transmit clock from the
SCK
pin is output without data transfer. This can be done only
while in internal clock mode.
When the status of the 1 and 0 bits (PMRA1, PMRA0) of port mode register A (PMRA: $004) is 00
while in transmit clock wait state, the state can be changed to continuous clock output state by enabling
the transmit clock (17). By writing to the serial mode register (SMR: $005) while in continuous clock
output state (18), the state will change to the STS wait state.
