Infrared Serial Communications Interface Module (IRSCI)
12.5.3.1 Character Length
The receiver can accommodate either 8-bit or 9-bit data. The state of the M bit in IRSCI control register 1
(IRSCC1) determines character length. When receiving 9-bit data, bit R8 in IRSCI control register 2
(IRSCC2) is the ninth bit (bit 8). When receiving 8-bit data, bit R8 is a copy of the eighth bit (bit 7).
