R
Description
Indicates that data reception has been completed and
the received data is in KBBR. When both KBIE and
KBF are set to1, an interrupt request is sent to the
CPU.
0: [Clearing condition]
Read KBF when KBF =1, then write 0 in KBF
1: [Setting conditions]
•
•
Indicates that an odd parity error has occurred.
0: [Clearing condition]
Read PER when PER =1, then write 0 in PER
1: [Setting condition]
When an odd parity error occurs
Keyboard Stop
Indicates the receive data stop bit. Valid only when
KBF = 1.
0: 0 stop bit received
1: 1 stop bit received
When data has been received normally and has
been transferred to KBBR while KBFSEL = 1
(keyboard buffer register full flag)
When a KCLK falling edge is detected while
KBFSEL = 0 (KCLK interrupt flag)
