[RESET output mask]

[Revision and vender]
These 3 bits are used as a signal to specify whether to produce the RESET when the respective DC-DC
converters are shut down.
No low signal is produced as the RESET even if Data (X)
of these bits is “L, L, L”.
(When a DC-DC converter is shut down, the RESET is driven low, and all DC-DC channels are turned off.)
If the DC-DC converter concerned is shut down:
A low signal is generated at the TH_OUT pin if the current temperature is X degrees lower than the TSD
temperature. In analog output mode, a very low voltage proportional to the temperature is generated.

(1) No RESET (ORT) is produced.
(2) All DC-DC converters other than that concerned operate normally (rather than being shut down)
(3) Changing the SLEEP signal from low to high restarts the DC-DC converter.
