MAP allows successive reads or writes of consecu-
tive registers. Each byte is separated by an ac-
knowledge bit.
Control Port Bit Definitions
All registers are read/write, except the Chip Status
register which is read-only. For more detailed in-
formation, see the bit definition tables starting on
page 19.
Power-up/Reset/Power Down Mode
Upon power up, the user should hold RST = 0 until
the power supplies and clocks stabilize. In this
state, the control registers are reset to their default
settings, and the device remains in a low power
mode in which the control port is inactive. The part
may be held in a low power reset state by clearing
the DIGPDN bit in the Chip Control register. In this
state, the digital portions of the CODEC are in re-
set, but the control port is active and the desired
register settings can be loaded. Normal operation is
achieved by setting the DIGPDN bit to 1, at which
time the CODEC powers up and normal operation
begins.
The CS4228 will enter a stand-by mode if the mas-
ter clock source stops for approximately 10
μ
s or if
the number of MCLK cycles per LRCK period var-
ies by more than 32. Should this occur, the control
registers retain their settings.
