Control Register
The control register (03hex) is a read/write register that
determines the device configuration. Bit 1 (IN1/IN2)
controls the input multiplexer, a logic high selects input
1, a logic low selects input 2. Bit 2 (HPS_D) controls the
headphone sensing. A logic low configures the device
in automatic headphone detection mode. A logic high
disables the HPS input. Bit 3 (GAINA/B) controls the
gain-select multiplexer. A logic low selects GAINA. A
logic high selects GAINB. GAINA/B is ignored when
HPS_D = 0. Bit 4 (SPKR/HP) selects the amplifier oper-
ating mode when HPS_D = 1. A logic high selects
speaker mode and a logic low selects headphone
mode.
