DESCRIPTION

GP5_LVL

GPIO 5 Level

(when GP5_FN = 00001)

0 = Logic 0

1 = Logic 1

Write to this bit to set the GPIO5

output. Read from this bit to read GPIO

input level.

Note that, when GPIO5 is configured

as an output (GP5_DIR=0), this is a

Write-Only register; the Readback

value is undefined.

4:0

GP5_FN[4:0]

0_0000

GPIO5 Pin Function select

0_0000 = Unused

0_0001 = Logic 0 or Logic 1

(depending on GP5_LVL)

0_0010 = SDOUT

0_0011 = IRQ

0_0100 = Temperature shutdown

0_0101 = Reserved

0_0110 = PLL2 Lock

0_0111 = PLL3 Lock

0_1000 = Reserved

0_1001 = FLL Lock

0_1010 = DRC Activity detect

0_1011 = Write Sequencer done

0_1100 = ALC Noise Gate active

0_1101 = ALC Peak Limiter overload

0_1110 = ALC Saturation

0_1111 = ALC level threshold

1_0000 = ALC Level lock

1_0001 = FIFO error indicator

1_0010 = OPCLK

1_0011 = Digital Microphone Clock

Output

1_0100 = Digital Microphone Data

Input

1_0100 = Reserved

1_0101 = Mic Detect flag

1_0110 = Mic Short Circuit flag

1_0111 to 1_1111 = Reserved

Note that GPIO5 functions are only

supported when CLKREG_OVD=1.

When CLKREG_OVD=0, the contents

of Register R516 must not be changed

from the default value.

R517 (0205h)

GPIO 6

GP6_DIR

GPIO6 Direction

0 = Output

1 = Input

GP6_PU

GPIO6 pull-up resistor enable

0 = pull-up disabled

1 = pull-up enabled

GP6_PD

GPIO6 pull-down resistor enable

0 = pull-up disabled

1 = pull-down enabled

GP6_POL

GPIO6 Polarity

0 = Not inverted

1 = Inverted
