First KCLK Falling Interrupt Flag
Indicates that the first falling edge of KCLK is detected.
When KCIE and KCIF are set to 1, requests the CPU
an interrupt.
0: [Clearing condition]
After reading KCIF = 1, 0 is written
1: [Setting condition]
When the first falling edge of KCLK is detected
Note that this flag cannot be set when software
standby mode or watch mode is cancelled. (However,
internal flag is set.)
1 KBTE 0 R/(W)
*
Transmit Completion Flag
Indicates that data transmission is completed. When
KTIE and KBTE are set to 1, requests the CPU an
interrupt.
0: [Clearing condition]
After reading KBTE = 1, 0 is written
1: [Setting Condition]
When all KBTR data has been transmitted (Set at the

0 KTER 0 R Transmit
Error
Stores a notification of receive completion. Valid only
