System Reset

The DLPA100 device can be reset by using the RESETZ input. This feature can be used during start-up conditions to reset the serial port registers to a known set of states. It can also be used during power-down conditions to disable certain features before complete shutdown occurs. The DLPC4422 display controller software controls which functions are reset to the power on reset (POR) state when RESETZ is initiated.

  • MSKFAN: Masks the reset of the 3 fan drivers (POR state = disabled, PWM=0%).
  • MSKREG: Masks the reset of linear regulators VLIN1 & VLIN2, and 5V switcher (POR state = enabled).
  • MSKMOT: Masks the reset of the motor controller configuration registers (POR state = 0).
  • MSKMOTE: Masks the reset of the motor controller output enable bit (POR state = disabled).
