DSP load timer value, 1/2 MSW
DSP read timer value, 1/2 LSW
DSP read timer value, 1/2 MSW
Function
Specifies what action the timer takes upon receiving a
suspend indication from the TIPB bridge. (For
example, suspend is indicated if processor execution
has been suspended at an emulation breakpoint.)
0: Stop counting on suspend indication (even when
ST=1).
1: A suspend indication has no effect on the count.
Enables input reference clock to the DSP OS timer
module
0: Disable
1: Enable
Prescale timer input reference clock
000: Divide input reference clock by 2
