* 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 preload 1 to 3
* Initialize the compare register to 0
* Control register 1:
* Enable timer1, no interrupts are enabled, TGATE signal has no effect.
* Use the selected clock for the counter clock, and enable it.
* Selected clock is 1/2 system's freq. Square-wave generation, toggle TOUT.

* MC68340 basic timer module register initialization example code.
* This code is used to initialize the 68340's internal timer module
* registers, providing basic functions for operation.
* It sets up timer1 for pulse-width measurement. In this mode, the number
* of clock cycles during a particular event are counted. The event is
* defined by the assertion and negation of TGATE.
