5 to 0 WaterLevel[5:0] denes, the warning level of a FIFO buffer overow or underow:
HiAlert is set to logic 1 if the remaining FIFO buffer space is equal to,
or less than, WaterLevel[5:0] bits in the FIFO buffer.
LoAlert is set to logic 1 if equal to, or less than, WaterLevel[5:0] bits in
the FIFO buffer.

the timer automatically restarts its countdown from the
TReloadValue[7:0] instead of counting down to zero
0
the timer decrements to zero and register InterruptIrq
TimerIRq bit is set to logic 1

TPreScaler[4:0]
-
denes the timer clock frequency (fTimerClock). The
TPreScaler[4:0] can be adjusted from 0 to 21. The following
formula is used to calculate the TimerClock frequency
(fTimerClock):
fTimerClock = 13.56 MHz / 2TPreScaler [MHz]
