TmrClk
This input must toggle at a rate of less than one half the
CPU core frequency (less than 100MHz in most cases). In
most cases this input toggles much slower (in the 1MHz to
10MHz range).

Signal Functional Description (Part 5 of 6)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3k
to 3.3V, 10k to 5V)
3. Must pull down (recommended value is 1k
)
4. If not used, must pull up (recommended value is 3k
to 3.3V)
5. If not used, must pull down (recommended value is 1k
)
6. Strapping input during reset; pull-up or pull-down required
