DESCRIPTION

IPVU

N/A

Input PGA Volume Update

Writing a 1 to this bit will cause left

and right input PGA volumes to be

updated (LINVOL and RINVOL)

LINMUTE

Left Input PGA Analogue Mute

1 = Enable Mute

0 = Disable Mute

Note: IPVU must be set to un-mute.

LIZC

Left Input PGA Zero Cross Detector

1 = Change gain on zero cross only

0 = Change gain immediately

R0 (00h)

Left Channel

PGA

5:0

LINVOL

[5:0]

( 0dB )

Left Input PGA Volume Control

111111 = +30dB

111110 = +29.25dB

. . 0.75dB steps down to

000000 = -17.25dB

N/A

Input PGA Volume Update

Writing a 1 to this bit will cause left

and right input PGA volumes to be

updated (LINVOL and RINVOL)

RINMUTE

Right Input PGA Analogue Mute

1 = Enable Mute

0 = Disable Mute

Note: IPVU must be set to un-mute.

RIZC

Right Input PGA Zero Cross

Detector

1 = Change gain on zero cross only

0 = Change gain immediately

( 0dB )

Right Input PGA Volume Control

111111 = +30dB

111110 = +29.25dB

. . 0.75dB steps down to

000000 = -17.25dB

TOEN

Timeout Enable (Also enables jack

detect debounce clock)

0 = Timeout disabled

1 = Timeout enabled

R23 (17h)

Additional

Control (1)

TOCLKSEL

Slow Clock Selection (Used for

volume update timeouts and for jack

detect debounce)

0 = SYSCLK / 2

21 (Slower

Response)

1 = SYSCLK / 2

19 (Faster

Response)

Table 4 Input PGA Volume Control

See "Volume Updates" for more information on volume update bits, zero cross and timeout

operation.

LINE INPUTS

Two pairs of stereo line inputs (LINPUT2 / RINPUT2 and LINPUT3 / RINPUT3) are available as

analogue inputs into the ADC path. LINPUT3 and RINPUT3 can also be input directly to the output

mixers via the bypass paths.

See "Output Signal Path" for more information on the bypass paths.
