Baud Detect Ratio. These bits are used to set the ratio of good to
bad baud detections which will be used as the minimum ratio to de-
termine that a valid signal is present on the medium. The value in
this register is treated as a radix 2 positive real number with two
decimal places. The lowest practical value possible is 0.25 (=00.01)
and the highest practical value is 3.75 (=11.11).
TCR22: Baud Detect Accept Count
This register is the Baud Detect Accept Count register. A
read-only register that indicates the current number of
good transitions detected by the baud detector.

Reserved. Must be written as a 0. Reads of this bit produce
undefined data.
Accept[5:0] The value of these bits indicates the current number
of good transitions detected by the baud detector. This is a
read-only register.

TCR23: Baud Detect Fail Count
This register is the Baud Detect Fail Count register. A
read-only register that indicates the current number of
bad transitions detected by the baud detector.

TCR24: RSSI Sample Start
This register is the RSSI Sample Start register. The
value in this register is used to determine when to cap-
ture a sample of the RSSI input for A/D conversion dur-
ing antenna diversity operation. The register value is a
measure of the time of RSSI sample relative to the an-
tenna switching event. A register value of 0 means that
no RSSI samples will be taken.
