71 - Register 24'h20004  PCI Interrupt Status
73  - bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
74  - gpio[16] pin into GP_SAMPLE register.
78 - Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
80 - set register 0x35C050 to  0xa80a80
81 - enable sampling
82 - set register 0x35C054 to 0x5
83 - enable the IRQ bit 18 in the interrupt mask register (and
91 bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
92 actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
96 as well.  Remember, this is a free running sample of the IR receiver state
97 over time, so don't assume any sample starts at any particular place.
