11.1 General
MC68336/376
USER’S MANUAL
The time processor unit (TPU) is an intelligent, semi-autonomous microcontroller de-
signed for timing control. Operating simultaneously with the CPU32, the TPU sched-
ules tasks, processes microcode ROM instructions, accesses shared data with the
CPU32, and performs input and output functions. Figure 11-1 is a simplified block di-
agram 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 CPU32 interrupt service. Two
sets of microcode ROM functions are currently available for most MCU derivatives
with the TPU.
The A mask set (or original mask set) includes the following functions:
• Discrete input/output
• Input capture/input transition counter
• Output compare
• Pulse width modulation
