PROGRAMMING AND CONFIGURATION
DESCRIPTION
SPI Commands from Microcontroller / Command Protocol
(Data into SI)
Table 5. SPI Command Protocol
SLEEP COMMAND
essentially turns the part OFF. By definition, a hardware reset
sends/keeps the IC in Sleep mode. All inputs are Tri-Stated,

U =Unknown value coming out of Sleep mode. It be must configured with
Run and Metallic commands. Note: the remaining combinations of bits
[16;13] are non-functional (0010. 0100. 0110. 0111).
MOD[2:1] = Operating mode
CP[4:1] = Configure programmable switch
TG[6:1] = Tri-State switch-to-ground
TB[2:1] = Tri-State switch-to-battery

Only a SPI command can take the IC out of Sleep mode.
Exiting this mode requires a valid Run, Tri-State, or Metallic
command.
