IR1 Transmit Carrier Wave Pulse High Register (IR1_CWPH)
IR2 Transmit Carrier Wave Pulse High Register (IR2_CWPH)
Offset = 0xBF0004 / 0xBF0084
Read/Write
Default = 0x1FFF0000
CWPH
Carrier Wave Pulse High
28:16
This register encodes the high pulse width of the IR car-
rier wave in units of sysclk cycles.
The actual carrier wave pulse high period is CWPH[12:0]
+ 1.
IR1 Modulated Signal Period Register (IR1_MSPR)
IR2 Modulated Signal Period Register (IR2_MSPR)
Offset = 0xBF0008 / 0xBF0088
Read/Write
Default = 0x0000 0000
This is one of two registers written to produce an IR output. The other
one is the IR Modulated Signal Pulse Low (IR_MSPL) register. Since this
register contains the enable bit that initiates the transmission, it must be
written last.

1 = The SIO_IRTX* output is active high, normally low.
0 = The SIO_IRTX* output is active low, normally high.
