Transmit Clock Error Detection (In External Clock Mode):
Serial interface 1 will malfunction if a
spurious pulse caused by external noise conflicts with a normal transmit clock during transfer. A transmit
clock error of this type can be detected as shown in figure 55.
If more than eight transmit clocks are input in transfer state, at the eighth clock including a spurious pulse
by noise, the octal counter reaches 000, the serial 1 interrupt request flag (IFS1: $003, bit 2) is set, and
transmit clock wait state is entered. At the falling edge of the next normal clock signal, the transfer state is
entered. After the transfer is completed and IFS is reset, writing to serial mode register 1A (SM1A: $005)
changes the state from transfer to STS wait. At this time serial interface 1 is in the transfer state, and the
serial 1 interrupt request flag (IFS1: $003, bit 2) is set again, and therefore the error can be detected.
Notes on Use:
Initialization after writing to registers: If port mode register A (PMRA: $004) is written to in transmit
clock wait state or in transfer state, serial interface 1 must be initialized by writing to serial mode
register 1A (SM1A: $005) again.
Serial 1 interrupt request flag (IFS1: $003, bit 2) set: For serial interface 1, if the state is changed from
transfer state to another by writing to serial mode register 1A (SM1A: $005) or executing the STS
instruction during the first low pulse of the transmit clock, the serial 1 interrupt request flag (IFS1:
$003, bit 2) is not set. To set the serial 1 interrupt request flag (IFS1: $003, bit 2), a serial mode register
1A (SM1A: $005) write or STS instruction execution must be programmed to be executed after
confirming that the
SCK
1
pin is at 1, that is, after executing the input instruction to port R4.
