Peripheral Simulation

For Silicon Laboratories, Inc. C8051T601 — Comparator 0

Simulation support for this peripheral or feature is comprised of:

  • Dialog boxes which display and allow you to change peripheral configuration.

These simulation capabilities are described below.

Comparator Dialog

Comparator

The Comparator Dialog controls simulation of the two voltage comparators in the device. When enabled, it allows the user to compare voltage sources to generate a logic-level signal to a variety of destinations.

Comparator 0

  • CPT0CN (Comparator 0 Control Register) contains the following control bit settings:
  • CP0EN (Comparator 0 Output Enable Bit) is set to enable comparator 0.
  • CP0OUT (Comparator 0 Output State Flag) is set when the voltage on CP0P is greater than CP0N.
  • CP0RIF (Comparator 0 Rising-Edge Interrupt Flag) is set when a Comparator 0 rising edge interrupt occurs.
  • CP0FIF (Comparator 0 Falling-Edge Interrupt Flag) is set when a Comparator 0 falling edge interrupt occurs.
  • CORSEF (Comparator 0 Reset Flag) is set to reset Comparator 0.
  • CP0HYP (Comparator 0 Positive Hysteresis Control Bits) selects 0, 2, 4 or 10 mV of positive hysteresis.
  • CP0HYN (Comparator 0 Negative Hysteresis Control Bits) selects 0, 2, 4 or 10 mV of negative hysteresis.
  • CPT0MX (Comparator 0 MUX Selection Register) contains the positive and negative input controls for CMX0P and CMX0N.
  • CMX0P (Comparator 0 Positive Input MUX Select) selects the port pins to be used for positive input.
  • CMX0N (Comparator 0 Negative Input MUX Select) selects the port pins to be used for negative input.
  • CP0P (Comparator 0 Positive Input Voltage) displays the Comparator 0 negative input voltage.
  • CP0N (Comparator 0 Negative Input Voltage) displays the Comparator 0 positive input voltage.
  • CPT0MD (Comparator 0 Mode Selection Register) selects the Comparator 0 response time.
