c. Timer Update: The counter/timer can initiate updates. First, disable interrupts and
updates (read base+4 and read base+6) and enable Simultaneous
Updates (read base+0). Then write the initial values into the DACs.
Program the counter/timer for the tick frequency (mode 2 or mode
4), initialize your ISR, enable updates (read base+5), and enable
interrupts (read base+3). This counter-generated update pulse is
available at the 40-pin header connector (OUT2) to synchronize
external devices.
