[Bit 6] OUTE (Output enable)
If this bit is set to "1", the pin TOTn is used as Reload Timer output. If this bit is set to "0" the timer
output TOTn is disabled.
[Bit 5] OUTL (Output level)
This bit sets the output level for the TOTn pin.
[Bit 4] RELD (Reload)
This bit enables reload operations.
When RELD is "1", the timer operates in reload mode. In this mode, the timer loads the reload register
contents into the counter and continues counting whenever an underflow occurs (when the counter value
changes from 0000
When RELD is "0", the timer operates in one-shot mode. In this mode, the count operation stops when an
underflow occurs due to the counter value changing from 0000

[Bit 3] INTE (Interrupt enable)
Timer interrupt request enable bit.
When INTE is "1", an interrupt request is generated when the UF bit changes to "1".
When INTE is "0", no interrupt request is generated, even when the UF bit changes to "1".
[Bit 2] UF (Underflow)
Timer interrupt request flag. UF is set to "1" when an underflow occurs (when the counter value changes
from 0000
effect. Read as "1" by read-modify-write instructions.
[Bit 1] CNTE (Count enable)
Timer count enable bit. Writing "1" to CNTE sets the timer to wait for a trigger. Writing "0" stops count
operation.
[Bit 0] TRG (Trigger)
Software trigger bit. Writing "1" to TRG applies a software trigger, causing the timer to load the reload
register content to the counter and starts counting.
Writing "0" has no effect. Reading always returns "0". Applying a trigger using this register is only valid
when CNTE = "1".
Writing "1" has no effect if CNTE = "0".
Set this bit in 'Gate Input mode' to load the reload register content before counting starts.
