5) Control registers
The control registers (16 bits) can be set via the microcomputer interface in addition to the control pins.
For the value to be written in the control registers, see the description of the microcomputer interface.
The following describes the control register map.
Control register map ( indicates the default values.)
Code
Function
C15
Selects the data reset function after reset is released. 0: Used
1: Unused
C14
Selects delay RAM sampling
0: 1Sampling
1: 2 Sampling
C13
Selects DRAM addressing method
0: Ring addressing
1: Linear addressing
C12
Random number generator circuit
0: Unused
1: Used
C11
Test mode (Use at 0)
0: Normal operation
1: Test mode
C10
Test mode (Use at 0)
0: Normal operation
1: Test mode
C9
Test mode (Use at 0)
0: Normal operation
1: Test mode
C8
Resets ADC section
0: Normal operation
1: Reset
C7
Sets internal path
0: ADC serial data selected
1: SDIN1 selected
C6
Sets internal path
0: Normal setting
1: Sets the path selected by C7
C5
DAC2 section reset control
0: Normal operation
1: DAC2 section reset
C4
DAC1 section reset control
0: Normal operation
1: DAC1 section reset
C3
SDOUT output enable
0: SDOUT = Output
1: SDOUT = "L"
C2
C1
Selects SDIN1 and SDIN2 input mode.
Mode

MSB first (24 bits)
LSB first (24 bits)
LSB first (20 bits)
LSB first (16 bit)
Note: When C = 1, the state is I
Select I
0: Normal setting
1: I
2
S compatible independent of mode setting; however, set to Mode 1.
C0
2
S compatible.
2
S compatible (In this case, all input/output pins are I
2
S compatible.)
Data can be loaded into the control registers only when DSP RESET = "L" and CODEC RESET = "L". If used
otherwise, an operation error will occur. To avoid an operation error, do not use it.
