Peripheral Simulation

For Infineon C508 — Compare Timer 1

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.

Compare Timer 1 Dialog

The Compare Timer 1 Dialog controls the time base for compare capture registers.

Compare Timer 1 Group

• Clock contains the value that is divided into the oscillator frequency to produce the compare timer 1 clock.
• CT1CON (Compare Timer Control Register) holds the clock selection settings, the interrupt and overflow flags.
• Status (Capture Timer Status) indicates the current state of the capture timer.
• CT1 (Compare Timer) holds the current 16-bit compare timer 1 value.
• CCP (Compare Timer Period Register) contains the period value to be matched with compare timer 1.
• CT1OF (Compare Timer 1 Offset Register) holds the value added to the compare timer to generate a delayed signal for outputs COUTx. CT1OF does not affect the CCx outputs.
• CT1R (Compare Timer 1 Run/Stop Control) when set, starts compare timer 1. Resetting this bit stops compare timer 1.
• CT1RES (Compare Timer 1 Reset Control) is set to clear the compare timer 1 value. If this bit is reset, the compare timer 1 value does not change when compare timer 1 is stopped (CT1R).
• STE1 (CAPCOM Unit Shadow Latch Transfer Enable) is set to transfer the period (CCP), compare (CC), and offset (CT1OF) registers into the real registers when compare timer 1 reaches the next timer event. STE1 is reset by hardware.
• CTM (Compare Timer 1 Operating Mode) is set for up/down counting, and reset for up counting only.

Interrupt Group

• ECT1 (Compare Timer 1 Interrupt Enable) is set to enable compare timer 1 interrupts.
• ECTP (Enable Compare Timer 1 Period Interrupt) is set to generate an interrupt and change the count direction when compare timer 1 reaches the period value.
• ECTC (Enable Compare Timer 1 Count Direction Change Interrupt Status) is set to generate an interrupt and change the count direction when compare timer 1 reaches 0.
• CT1FP (Compare Timer 1 Period Flag) is set when compare timer 1 reaches the period value. If CTM is set, the count direction changes also. This flag must be cleared by software.
• CT1FC (Compare Timer 1 Count Direction Change Flag) is set when compare timer 1 reaches 0 and changes the count direction. This flag must be cleared by software.
