Software-Related Considerations
■
Timer 2 can generate a DMA request. For more information, see Chapter 8, “DMA
Controller.”
■
Timer 0 and Timer 1 each have two 16-bit count compare registers. These registers can
be used together to expand the time resolution for the timers. For more information, see
the Timer Mode and Control registers in the
Am186™CC/CH/CU Microcontrollers
Register Set Manual, order #21916.
10.5.9
Comparison to Other Devices
The programmable timers are 100% compatible with the timers in the Am186ES and
Am186ED microcontrollers.
10.6
INITIALIZATION
On both an external and internal reset, the following occurs:
■
The values of all the timer registers are cleared to 0000h.
■
All the timer signals default to PIO operation (see Table 10-1 on page 10-2).
■
The PWD bit in the SYSCON register is cleared to 0.
