In Full Chip Simulation (FCS) mode, this module lets you simulate all the functionality of the Time Of Day (TOD) module. The module includes an 8-bit counter, a 6-bit match register, several binary-based and decimal-based prescaler dividers, three clock source options, and one interrupt that can be used for quarter second, one second and match conditions. A 4 Hz signal is used as the reference clock for the TOD counter, where each tick of the TOD counter is 0.25 seconds. This module can be used for time-of-day, calendar, or any task scheduling functions. It can also serve as a cyclic wake up from low-power modes without the need for external components.
