T2StopRx
If set to 1 the timer stops immediately after receiving the first data. Set
to logic 0, indicates, that the timer is not stopped automatically.
Note: If LFO Trimming is selected by T2Start, this bit has no effect

5 to 4
T2Start
00b: The timer is not started automatically.
01b: The timer starts automatically at the end of the transmission.
10b: Timer is used for LFO trimming without underflow (Start/Stop on
PosEdge).
11b: Timer is used for LFO trimming with underflow (Start/Stop on
PosEdge).

T2AutoRestart Set to logic 1, the timer automatically restarts its countdown from
TnReloadValue, after the counter value has reached the value zero.
Set to logic 0 the timer decrements to zero and stops. The bit
Timer2IRq is set to logic 1 when the timer reaches zero

T2Clk
00b: The timer input clock is 13.56 MHz.
01b: The timer input clock is 212 kHz.
10b: The timer input clock is an underflow of timer 0
11b: The timer input clock is an underflow of timer 1

T2ReloadHi
Defines the high byte of the reload value of the timer 2. With the start
event the timer load the value of the T2ReloadValHi_Reg and
T2ReloadValLo_Reg. Changing this register affects the timer only at
the next start event.
