Operational Description
7.1 RESET
The HSCX is forced into the reset state if a high signal is input to the RES pin for a minimum
period of 1.8
s. During RESET, the HSCX is temporarily in the power-up mode, and a subset
of the registers is initialized with defined values.
After RESET, the HSCX is in power down mode, and the following registers contain defined
values:
