Fault detect recovery bypass
Table 15.
The on-chip power block provides feedback to the digital controller which is used to indicate
a fault condition (either overcurrent or thermal). When fault is asserted, the power control
block attempts a recovery from the fault by asserting the 3-state output, holding it for period
of time in the range of 0.1 ms to 1 second, as defined by the fault-detect recovery constant
register (FDRC registers 0x2B-0x2C), then toggling it back to normal condition. This
sequence is repeated as log as the fault indication exists. This feature is enabled by default
but can be bypassed by setting the FDRB control bit to 1. The fault condition is also
asserted by a low-state pulse of the normally high INT_LINE output pin.
Configuration register B (addr 0x01)
Serial audio input interface format
Table 16.
Serial data interface
The STA339BWS audio serial input interfaces with standard digital audio components and
accepts a number of serial data formats. STA339BWS always acts as slave when receiving
audio input from standard digital audio components. Serial data for two channels is provided
using three inputs: left/right clock LRCKI, serial clock BICKI, and serial data SDI.
Bits SAI and bit SAIFB are used to specify the serial data format. The default serial data
format is I
