REV. A
PNPR
Plug and Play Reset flag. T his bit is set by an AD1816A reset (RESET B pin asserted LOW) or by a Plug and Play
reset command. T his bit is cleared by the assertion of the FCLR bit in the control word. While this bit is set, all at-
tempts to write an SS indirect register via the DSP port will be ignored and fail. T his is to ensure that Plug and
Play resets are immediately applied to the application running on the DSP, without requiring them to continuously poll
the Plug and Play reset status bit. During the frame in which this bit is cleared (by asserting FCLR), an attempt to
write an SS indirect register will succeed. If the FCLR bit is continuously asserted, writes to indirect registers via
the DSP port will always be enabled. A Plug and Play reset command will set this PNPR bit HIGH during at least
one frame.
Power-Down flag. T his bit is set by an AD1816A reset (RESET B pin asserted LOW), or by an AD1816A power-
down. Before an AD1816A power-down sequence shuts down the DSP port, at least one frame will be sent with
this bit set. T his bit can be cleared by the assertion of the FCLR (DSP port status clear) bit in the control word,
providing the AD1816A is no longer in power-down.
T he SDFS pin is used for the serial interface frame synchronization. New frames are marked by a one SCLK duration HI pulse,
driven out on SDFS, one serial clock period before the frame begins. Upon initializing, there are exactly 12 time slots per frame and
16 bits per time slot. T he frame rate is 57,291 and 2/3 Hz (11 MHz SCLK /(16 bits
×
12 slots)). T he frame rate can also be changed
from the default value by reprogramming the rate in registers. T he frame rate can run at the default rate or be programmed to match
the modem sample rate, ADC capture rate, DAC playback rate, music sample rate, I
2
S(1) sample rate or I
2
S(0) sample rate. When
the frame rate is not equivalent to the sample rate, Valid Out, Request In and Valid In bits are used to control the sample data flow.
When the frame rate is equivalent to the sample rate, Valid and Request bits can be ignored.
