20.2.4
KBCOMP is an 8-bit readable/writable register that controls the SCI2 IrDA function and selects
the CIN input channels for A/D conversion.
KBCOMP is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 4—IrDA Control: See the description in section 15.2.11, Keyboard Comparator Control
Register (KBCOMP).
Bit 3—Keyboard A/D Enable (KBADE): Selects either analog input pins (AN6, AN7) or digital
input pins (CIN0 to CIN7, CIN8 to CIN15) for A/D converter channel 6 and channel 7 input.
Bits 2 to 0—Keyboard A/D Channel Select 2 to 0 (KBCH2 to KBCH0): These bits select the
channels for A/D conversion from among the digital input pins. Only set the input channel while
A/D conversion is stopped.
