Description

[15]

GPIO_DAC_MODE

When any GPIO_CFG is "System mode control":

• 1'b0: Disable datapath when GPIO input is 1'b1

• 1'b1: Enable datapath when GPIO input is 1

When GPIOx input is 1'b0, system mode is determined by

[14:7]

RESERVED

N/A

[6]

GPIO_SEL

Outputs a specific channel's flag if the corresponding

GPIO_AND and GPIO_OR are not set.

• 1'b0: Outputs status/flag from CH1

• 1'b1: Outputs status/flag from CH2

[5]

GPIO_OR_SS_RAMP

Sets the GPIO_CFG "Soft Ramp Done" flag output as the

bitwise OR of both channel's flags.

• 1'b0: Disabled (default)

• 1'b1: Enabled, GPIO_CFG output is |(ss_full_ramp[CHx])

[4]

GPIO_OR_VOL_MIN

Sets the GPIO_CFG "Automute Status" output as the bitwise

OR of both channel's statuses.

• 1'b0: Disabled (default)

• 1'b1: Enabled, GPIO_CFG output is |(automute[CHx])

[3]

GPIO_OR_AUTOMUTE

Sets the GPIO_CFG "Minimum Volume" flag output as the

bitwise OR of both channel's flags.

• 1'b0: Disabled (default)

• 1'b1: Enabled, GPIO_CFG output is |(vol_min[CHx])

[2]

GPIO_AND_SS_RAMP

Sets the GPIO_CFG "Soft Ramp Done" flag output as the

bitwise AND of both channel's flags.

• 1'b0: Disabled

• 1'b1: Enabled, GPIO_CFG output is &(ss_full_ramp[CHx])

(default)

Note: Overridden by GPIO_OR_SS_RAMP.

[1]

GPIO_AND_VOL_MIN

Sets the GPIO_CFG "Automute Status" output as the bitwise

AND of both channel's statuses.

• 1'b0: Disabled

• 1'b1: Enabled, GPIO_CFG output is &(automute[CHx])

(default)

Note: Overridden by GPIO_OR_AUTOMUTE.

[0]

GPIO_AND_AUTOMUTE

Sets the GPIO_CFG "Minimum Volume" flag output as the

bitwise AND of both channel's flags.

• 1'b0: Disabled

• 1'b1: Enabled, GPIO_CFG output is &(vol_min[CHx])

(default)

Note: Overridden by GPIO_OR_VOL_MIN.
