FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Description: This register controls:
- The state of HS1 in stop and sleep mode (HS1 permanently off or HS1 cyclic)
- Enable or Disable the forced wake-up function (SBC automatic wake-up after time spend in sleep or stop mode, time defined
- Enable or disable the sense of the wake-up inputs (LX) at sampling point of the cyclic sense period (LX2HS1 bit).
