Configuration of the timer T0 clock.
Prescaler is disabled: the timer frequency matches CLIF
clock frequency (13.56 MHz).
Prescaler is enabled: the timer operates on the prescaler
signal frequency (chosen by T0_PRESCALE_SEL).
If set to 0, the timer T0 will stop on expiration.
After expiration, the timer T0 will stop counting, i.e., remain
zero, reset value.
After expiration, the timer T0 will reload its preset value and
continue counting down.
Enables the timer T0
Description
T1_STOP_EVENT: If set the timer T1 is stopped when timer
T3 raises its expiration flag.
T1_STOP_EVENT: If set the timer T1 is stopped when a
data reception begins (1st bit is received).
T1_STOP_EVENT: If set the timer T1 is stopped when a
data transmission begins.
T1_STOP_EVENT: If set the timer T1 is stopped when the
external RF field is detected.
T1_STOP_EVENT: If set the timer T1 is stopped when the
external RF field vanishes.
T1_STOP_EVENT: If set, the timer T1 is stopped when the
internal RF field is turned on.
T1_STOP_EVENT: If set, the timer T1 is stopped when the
internal RF field is turned off.
T1_STOP_EVENT: If set, the timer T1 is stopped when an
activity on SigIn is detected.
Reserved
T1_START_EVENT: If set, the timer T1 is started when the
timer T3 starts running.
