Function:
Soft Volume Ramp-up after Reset (Bit 3)
Soft Ramp-down before Reset (Bit 2)
This function allows the user to control whether a soft ramp up in volume is applied when reset is re-
leased either by the reset pin or internal to the chip. The modes are as follows:
0 - An instantaneous change is made from max attenuation to the control port volume setting on re-
lease of reset (default setting).
1 - Volume is ramped up using the soft-ramp settings in Bits 6:5 of register 02h (see 6.2.2) from max
attenuation to the control port volume setting on release of reset.
This function allows the user to control if a soft ramp-down in volume is applied before a known reset
condition. The modes are as follows:
0 - An instantaneous change is made from the control port volume setting to max attenuation when
chip resets (default setting).
1 - Volume is ramped down using the soft-ramp settings in Bits 6:5 of register 02h (see 6.2.2) from
the control port volume setting to max attenuation when chip resets.
This register is Read-Only. Bits 7 through 4 are the part number ID which is 1000b (8h) and the re-
maining Bits (3 through 0) are for the chip revision.
