BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R 00000000 Reserved. Do not write to these registers.
Page 1 / Register 0: Page Select Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D1 X 0000000 Reserved, write only zeros to these register bits
D0 R/W 0 Page Select Bit
Writing zero to this bit sets Page-0 as the active page for following register accesses. Writing a one to
this bit sets Page-1 as the active page for following register accesses. It is recommended that the user
read this register bit back after each write, to ensure that the proper page is being accessed for future
register read/writes. This register has the same functionality on page-0 and page-1.
Page 1 / Register 1: Left Channel Audio Effects Filter N0 Coefficient MSB Register
(1)
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R/W 0x6B Left Channel Audio Effects Filter N0 Coefficient MSB
The 16-bit integer contained in the MSB and LSB registers for this coefficient are interpreted as a 2 ’ s
complement integer, with possible values ranging from – 32768 to +32767.
(1) Note that whenever any coefficient value is changed, the MSB register should be written first, immediately followed by theLSB register.
Even if only the MSB or LSB of the value changes, both registers should be written
Page 1 / Register 2: Left Channel Audio Effects Filter N0 Coefficient LSB Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R/W 0xE3 Left Channel Audio Effects Filter N0 Coefficient LSB
The 16-bit integer contained in the MSB and LSB registers for this coefficient are interpreted as a 2 ’ s
complement integer, with possible values ranging from – 32768 to +32767.
Page 1 / Register 3: Left Channel Audio Effects Filter N1 Coefficient MSB Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7-D0 R/W 0x96 Left Channel Audio Effects Filter N1 Coefficient MSB
The 16-bit integer contained in the MSB and LSB registers for this coefficient are interpreted as a 2 ’ s
complement integer, with possible values ranging from – 32768 to +32767.
