Peripheral Simulation

For Infineon XC888C-8FF — Capture/Compare Unit 6 (CCU6)

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.

CCU6 Capture Compare Dialog

The CCU6: Capture/Compare Dialog controls the compare and capture functions. The compare function generates an output signal when a compare timer equals a preset value. The capture function stores a capture timer value based on an external signal.

Capture/Compare Channels

• CC6xR (Capture/Compare Registers 0-2) are read-only registers that hold the target compare or capture values.
• CC6xSR (Capture/Compare Shadow Registers 0-2) contain the next value to be stored by the CCU into CC6xR.

Dead Time Control

• T12DTC (Timer T12 Dead-Time Control Register) contains the dead-time control bit setting below:
• DTM (Dead-Time) is an 8-bit down count that defines the delay between passive to active states for the Timer 12 compare channel.
• DTEx (Dead-Time Enable Bits) are set to allow dead-time generation for each capture/compare channel (0-2).
• DTRx (Dead-Time Run Indication Bits) are set when a dead-time counter is non-zero.

Mode

• T12MSELx (T12 Capture/Compare Mode Select Register) contains the MSEL6x bits described below.
• MSEL6x (Capture/Compare Mode Select Register 0-2) selects one of the capture or compare operating modes.

Compare Channel

• CC63R (Capture/Compare Registers for Channel 63) are read-only registers that hold the target compare values compared to Timer 13.
• CC63SR (Capture/Compare Shadow Registers for Channel 63) contain the next value to be stored by the CCU into CC63R.

Port Input Select Register

• PISEL0 (Port Input Select Register 0) contains the port input pin selection definitions for capture modules CC60-CC62 and CCPOS0-CCPOS2.

• MCC6xS and MCC6xR (Capture/Compare Status Modification Bits) are used to change output line status by setting (using MCC6xS) or resetting (using MCC6xR) the CC6xST bits.
• CC6xPS and COUT6xPS (Passive State Select for Compare Outputs)
• when set, the compare output drives the passive level when CC6xST is set.

Port Pins Group
