Register 16, TV Remote Receive Timing Register #1
Register 17, TV Remote Receive Timing Register #2
Register 18, TV Remote Receive Timing Register #3
For TV remote receive "oversampled" mode, this register value determines the input data sample rate.
The sample rate is 3.6864 MHz divided by this register value. The sample rate should be set to as fast
as possible, to give the best resolution on the incoming data edges, but should be less than 80% of the
main UART communication baud rate.
For TV remote receive "programmed T period" mode, this register sets the expected incoming bit cell
time (T). The main UART communications rate must be set to at least 20% greater than 1/T.
