Page 0 / Register 13: Headset / Button Press Detection Register A (continued)
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D1-D0 R/W 00 Headset Glitch Suppression Debounce Control for Button Press
00: Debounce = 0msec
01: Debounce = 8msec(sampled with 1ms clock)
10: Debounce = 16msec(sampled with 2ms clock)
11: Debounce = 32msec(sampled with 4ms clock)
Page 0 / Register 14: Headset / Button Press Detection Register B
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 Driver Capacitive Coupling
0: Programs high-power outputs for capless driver configuration
1: Programs high-power outputs for ac-coupled driver configuration
D6
(1)
R/W 0 High Power Stereo Output Driver Configuration A
Note: do not set bits D6 and D3 both high at the same time.
0: A stereo fully-differential output configuration is not being used
1: A stereo fully-differential output configuration is being used
D5 R 0 Button Press Detection Flag
This register is a sticky bit, and will stay set to 1 after a button press has been detected, until the
register is read. Upon reading this register, the bit is reset to zero.
0: A button press has not been detected
1: A button press has been detected
D4 R 0 Headset Detection Flag
0: A headset has not been detected
1: A headset has been detected
D3
(1)
R/W 0 Stereo Output Driver Configuration B
Note: do not set bits D6 and D3 both high at the same time.
0: A stereo pseudo-differential output configuration is not being used
1: A stereo pseudo-differential output configuration is being used
D2 – D0 R 000 Reserved. Write only zeros to these bits.
(1) Do not set D6 and D3 to 1 simultaneously
Page 0 / Register 15 – 24: Reserved Registers
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R/W 00000000 Reserved. Only write zeroes to these bits.
Page 0 / Register 25: MICBIAS Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D6 R/W 00 MICBIAS Level Control
00: MICBIAS output is powered down
01: MICBIAS output is powered to 2.0 V
10: MICBIAS output is powered to 2.5 V
11: MICBIAS output is connected to AVDD_DAC
D5 – D3 R 000 Reserved. Write only zeros to these register bits.
D2 – D0 R XXX Read only bits. Do not write to these register bits.
Page 0 / Register 26 – 36: Reserved Registers
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 – D0 R/W 00000000 Reserved. Only write zeroes to these bits.
