EDGnB and EDGnA — Input Capture Edge Control Bits
12.3.7 Timer Interrupt Mask Registers
Read: Anytime
Write: Anytime
The bits in TMSK1 correspond bit-for-bit with the bits in the TFLG1 status register. If cleared, the
corresponding flag is disabled from causing a hardware interrupt. If set, the corresponding flag is enabled
to cause a hardware interrupt.
