Timer clock cycle time
Input Setup to timer clock
Input Hold from timer clock
Output clock to output valid
Timer alarm to output valid
Notes:
1. The timer can operate on rtc_clock or tmr_clock. These clocks get muxed and any one of them can be selected. Min and
2. These are asynchronous signals.
3. Inputs need to be stable at least one TMR clock.
Max requirement for both rtc_clock and tmr_clock are the same.
