Texas Instruments TAS3002 manual Main Control Register 1 01h, Main Control Register 2 43h

4.12 Main Control Register 1 (01h)

The TAS3002 device contains two main control registers: main control register 1 (MCR1) and main control register 2 (MCR2). The MCR1 register contains the bits associated with load speed, SCLK frequency, serial-port mode, and serial-port word length. It is accessed via I2C with the address 01h.

BIT	FIELD NAME	TYPE			DESCRIPTION
7	FL	R/W	Fast load
			0	= Normal operation mode
			1	= Fast -load mode (default)
6	SC	R/W	SCLK frequency
			0	= SCLK is 32 fS.
			1	= SCLK is 64 fS.
5−4	E	R/W	Serial port mode
			00		= Left justified
			01		= Right justified
			10		= I2S
			11 = Reserved
3−2	Reserved	R	Reserved
1−0	W	R/W	Serial port word length
			00		= 16-bit
			01		= 18-bit
			10		= 20-bit
			11 = 24-bit

4.13 Main Control Register 2 (43h)

The TAS3002 device contains two main control registers: main control register 1 (MCR1) and main control register 2 (MCR2). The MCR2 register contains the bits associated with the AllPass function and the download of bass and treble control information, and it is accessed via I2C with the address 43h.

MCR2 (43h)

Bit	7	6	5	4	3	2	1	0

Default	0	0	0	x	x	x	0	0

Table 4−3. Main Control Register 2 Description

BIT	FIELD NAME	TYPE		DESCRIPTION
7	Reserved	R/W	0	= Normal operation (initial condition after reset)
			1	= Download bass and treble
6−5	Reserved	R	Reserved. Bits 6 and 5 return 0s when read.
4−2	Reserved	R	Undefined.
1	DM(1−0)	R/W	0	= Normal operation (initial condition after reset)
			1	= AllPass mode (bass and treble are still functional)
0	INP	R	Reserved. Bit 0 returns 0 when read.
