Section 15 Serial Communication Interface (SCI, IrDA)
15.2.11 Keyboard Comparator Control Register (KBCOMP)
KBCOMP is an 8-bit readable/writable register that selects the functions of SCI2 and the A/D
converter.
KBCOMP is initialized to H'00 by a reset and in hardware standby mode.
Bit 7—IrDA Enable (IrE): Specifies normal SCI operation or IrDA operation for SCI2
input/output.
