To be noted that register 0x47 is meaningful only after the EAPD bit is set to ‘1’ at least
once.
The short-circuit protections implemented are effective only in BTL configuration, and they
must not be activated if a single ended-application scheme is needed.

In
in clock cycles, where the clock frequency is defined as in section 7.1.1. The gray color is
used for the SHOKx bits to indicate that the bits are carrying the status of the previous
EAPD 0->1 toggling (to be noted that after reset this state is meaningless since no EAPD
transition occurs). GND-related SHOK bits are updated as soon as the gnd test is
completed, VCC bits are updated after the vcc test is completed, and the SOUT bit is
updated after the shorted output test is completed. The gnd test, vcc test and output test are
always run (if the SHEN bit active and EAPD is toggled to ‘1’), and only if both tests are
successful (no short) do the bridge outputs leave the tristate (indicated by dotted lines in the
figure). If one of the three tests (or all) fail, the power bridge outputs are kept in tristate until
the procedure is restarted with a new EAPD toggling.
In this figure EAPD is intended to be bit 7 of register 0x05.
Extended coefficient range up to -4...4 (address 0x49, 0x4A)
