FRONT PANEL AND MISCELLANEOUS CONTROL SIGNALS
This Chapter describes the various SAA7390 control signals; front panel and basic engine signals, jumper settings and
use of the general purpose signals.
Table 14
Start clock doubler: 0xF091
A write of any value to this address will engage the clock doubler. The state of the doubler may be obtained by reading
C_34_16 in BRGSEL (see Table 26). If this bit is set then the clock doubler is engaged. On power-on, the clock doubler
is disabled. Once the clock doubler is engaged, it can only be reset by one of the reset sources; a power-on reset, an
SCSI reset or a reset from the watch-dog timer. The clock doubler must not be engaged when a 34.8688 MHz clock is
connected to OSCIN (pin 120).
Table 15
General logic control register: 0xF0B9; note 1
Note
1.
Register 0xF0B9 controls the audio mixing, the LED and the PWM control.
Table 16
WTGCTL field descriptions
Table 17
Drive switches register: 0xF0BA; note 1
Note
1.
Register 0xF0BA is used for sensing the drive switches (note that the meaning of the switches is application specific).
