Programming (continued)
For example, at device reset, the active page defaults to page 0, and thus all register read/write operations for
addresses 1 to 127 access registers in page 0. If registers on page 1 must be accessed, the user must write the
8-bit sequence 0x01 to register 0, the page control register, to change the active page from page 0 to page 1.
After this write, it is recommended that the user also read back the page control register, to ensure the change in
page control has occurred properly. Future read/write operations to addresses 1 to 127 now access registers in
page 1. When page-0 registers must be accessed again, the user writes the 8-bit sequence 0x00 to register 0,
the page control register, to change the active page back to page 0. After a recommended read of the page
control register, all further read/write operations to addresses 1 to 127 access page-0 registers again.

10.6.1 Control Registers
The control registers for the TLV320AIC3107 are described in detail below. All registers are 8 bit in width, with
D7 referring to the most significant bit of each register, and D0 referring to the least significant 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.
(1) When resetting registers related to routing and volume controls of output drivers, it is recommended to reset them by writing directly to
the registers instead of using software reset.
