7.1 General

USER’S MANUAL
I M B
The time processor unit (TPU) is an intelligent, semi-autonomous microcontroller de-
signed for timing control. Operating simultaneously with the CPU, the TPU schedules
tasks, processes ROM instructions, accesses shared data with the CPU, and performs
input and output. Figure 7-1 is a simplified block diagram of the TPU.
The TPU can be viewed as a special-purpose microcomputer that performs a pro-
grammable series of two operations, match and capture. Each occurrence of either
operation is called an event. A programmed series of events is called a function. TPU
functions replace software functions that would require host CPU interrupt service.
The following pre-programmed timing functions are currently available:
• Input capture/input transition counter
• Output compare
• Pulse-width modulation
• Synchronized pulse-width modulation
• Period measurement with additional transition detect
• Period measurement with missing transition detect
• Position-synchronized pulse generator
• Stepper motor
• Period/pulse-width accumulator
