24.5.4.4 Current Timer Value Register (CVAL)
This register indicates the current timer position.
24.5.4.5 Timer Control Register (TCTRL)
This register contains the control bits for each timer.
Table 24-26. LDVAL field descriptions
Field Description
TSV Time Start Value
This field sets the timer start value. The timer counts down until it reaches 0, then it generates an interrupt
and loads this register value again. Writing a new value to this register does not restart the timer, instead
the value is loaded once the timer expires. To abort the current cycle and start a timer period with the new
value, the timer must be disabled and enabled again (see Figure 24-63).

Field Description

This field represents the current timer value. Note that the timer uses a downcounter.
Note: The timer values will be frozen in Debug mode if the FRZ bit is set in the PIT Module Control
Register (see Figure 24-2).
