Product specification
CD audio decoder, digital servo and filterless
DAC with integrated pre-amp and laser control
SAA7826
Table 55
defect_parm parameter: defect detector control
Table 56
interrupt_mask parameter: mask to enable
interrupt in interrupt status register; RAM
address 53H
Table 57
time_parameter: timer interrupt values
Note
1.
The time_parameter values are also used for
focus_start_time, motor_start_time1,
motor_start_time2, radial_init_time and brake_time.
Table 58
phase_shift parameter: focus/radial AGC
detection phase shift; RAM address 67H
Note
1.
The value a is the value programmed in Table 60 as
the 6 LSBs of osc_inc.
