Description
Keyboard In/Out Enable
Selects whether or not the keyboard buffer control unit
is used.
0: The keyboard buffer control unit is non-operational
1: The keyboard buffer control unit is enabled for
Keyboard Clock In
Monitors the KCLK I/O pin. This bit cannot be
modified.
0: KCLK I/O pin is low
1: KCLK I/O pin is high
Keyboard Data In
Monitors the KDI I/O pin. This bit cannot be modified.
0: KD I/O pin is low
1: KD I/O pin is high
Keyboard Buffer Register Full Select
Selects whether the KBF bit is used as the keyboard
buffer register full flag or as the KCLK fall interrupt
flag. When KBF bit is used as the KCLK fall interrupt
flag, the KBE bit in KBCRL should be cleared to 0 to
disable reception.
0: KBF bit is used as KCLK fall interrupt flag
1: KBF bit is used as keyboard buffer register full flag
Keyboard Interrupt Enable
Enables or disables interrupts from the keyboard
buffer control unit to the CPU.
0: Interrupt requests are disabled
1: Interrupt requests are enabled
(KCLK and KD signal pins have port functions)
transmission and reception (KCLK and KD signal
pins are in the bus drive state)
