REGISTER 7: LCH_CFG (SHORT-CIRCUIT LATCH-OFF
AND OVERVOLTAGE LATCH-OFF CONFIGURATION),
ADDRESS 0x07
Register 7 is used to enable and disable the latch-off function for
short-circuit protection (SCP) and overvoltage protection (OVP).
When the SCP or OVP latch-off function is enabled, the
CHx_LCH bit in Register 12 is set after an error condition
occurs (see the Latch-Off Protection section). The default value
for the SCP latch-off and OVP latch-off functions can be
programmed by factory fuse (SCP or OVP latch-off function
enabled or disabled for all four buck regulators).
