Timer-tick_interval
This value controls the interval between timer tick events. The timer ticks are
internally generated by counting sysclk pulses. The count of sysclk pulses
between sysclk pulsesis a 26 bit integer, the most significant 16 bits of which
are specified here, and the lower 10-bits are set to ‘0’s internally. To give an
example, a Timer_tick_interval value of
0 x 3473 represents a value of 0XD1CC00 (13,749,248 decimal) sysclk
pulses; this translates to about 275 milliseconds in real time assuming a 50
MHz sysclk.
