;This Initialization Routine performs the following Functions:

;

;1. Disable interrupt.

;2. Zeros all accumulators.

;3. Clears memory

;4. Starts PLL with clock frequency defined by PLLMBITS. Appropriately

;sets the RTO trim bits (for C614 only). Switch to idle mode for 200ms

;for PLL to stabilize.

;5. If DAC interrupt is replaced by Timer 1 interrupt, the period of

;timer 1 is stored in TIM1 register.

;6. Zeros all system registers except R7 (STACK).

;

;Turn off TIMER 2 rather than leave it running.

;Modified to cope with 6 bit trim value. Top 5 bits go to bits

;15±11 in ClkSpdCtrl, LSB of trim goes to bit 9 in ClkSpdCtrl.

;A fairly basic but compact initialization routine for the 614.

;This sets the 614 to run at 8 MHz, 10 bit DAC at 8 kHz.
