26.3.2.2.9 Timer 1 Configuration Register (T1C)
This relative timer generates an interrupt on the non maskable interrupt signal CC_tint1 after the specified
number of macroticks has expired.
Timer 1 can be activated as long as the POC is either in NORMAL_ACTIVE state or in
NORMAL_PASSIVE state. Timer 1 is deactivated when leaving NORMAL_ACTIVE state or
NORMAL_PASSIVE state except for transitions between the two states.
Before reconfiguration of the timer, the timer has to be halted first by writing bit T1RC to 0.
Figure 26-125 and Table 26-104 illustrate this register.
