SLWS115E – OCTOBER 2001 – REVISED JANUARY 2007
Figure 38. Turbo Programming Mode (SCLK Is Not Drawn To Scale)
The TLV320AIC1x contains six control registers that are used to program available modes of operation. All
register programming occurs during the control frame through DIN. New configuration takes effect after a delay
of one frame sync FS except the software reset, which happens after 6 MCLKs from the falling edge of the next
frame sync FS. The TLV320AIC1x is defaulted to the programming mode upon power up. Set bit 6 in control
register 1 to switch to continuous data transfer mode. If the 15+1 data format of DIN has been selected, the LSB
of the DIN to 1 to switch from continuous data transfer mode to programming set mode. Otherwise, either the
device needs to be reset or the host port writes 0 to bit D6 of control register 1 during the continuous data
transfer mode to switch back to the programming mode.
