Power-down delay selector (PNDLSL[2:0]) bits (address 0x4C, bit D4,
D3, D2)
As per
million clock cycles puts the power bridge in tristate mode, independently from the fade-out
time. Using these registers it is possible to program this counter according to the following
table.
Table 171. PNDLSL bits configuration
Short-circuit check enable bit (address 0x4C, bit D0)
This bit, when enabled, will activate the short-circuit checks before any power bridge
activation (EAPD bit 0->1). See section
