PRODUCTION DATA
IrDA modes only.
The registers RXFLL and RXFLH hold the 12-bit receive maximum frame length. RXFLL holds the least significant bits and RXFLH holds the most significant bits. If the intended maximum receive frame length is n bytes, then program RXFLL and RXFLH to be n + 3 in SIR or MIR modes and n + 6 in FIR mode (+3 and +6 are due to frame format with CRC and stop flag; there are two bytes associated with the FIR stop flag).
