***************************************************************************
* Initialize Timer1
***************************************************************************
* Disable timer1
* Allow TGATE to negate and assert so that an accurate count will result.
* If SR1 TGL bit=1, continue looping. TGATE is negated.
* If TGL bit=0, continue looping. TGATE is asserted.
* Ready to initialize timer1, TGATE is negated.
* Module configuration register:
* Timer1 module is set for normal operation, ignore FREEZE.
* Supervisor/user timer1 registers unrestricted.
* Interrupt arbitration at priority $03.
* Initialize timer1 interrupt level to 2 and vector to $0F
* Initialize the compare register to 0
* Clear the SR1 TG bit (by writing a 1) to use as a flag
* Control register 1:
* Enable timer1, no interrupts are enabled, TGATE signal used to control
* the counter. Use the selected clock for the counter clock, and enable it.
* Selected clock is 1/2 system's freq. Pulse-width measurement,
* disable TOUT.
