USER’S MANUAL
The following section provides general information on the time processor unit 2
(TPU2), an enhanced version of the TPU. The TPU2 is an intelligent, semi-autono-
mous microcontroller designed for timing control. Operating simultaneously with the
CPU16, the TPU2 schedules tasks, processes microcode ROM instructions, accesses
shared data with the CPU16, and performs input and output functions. Figure 14-1 is
a simplified block diagram of the TPU.
The TPU2 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 CPU16 interrupt service. Two
sets of microcode ROM functions are currently available for most MCU derivatives
with the TPU2.
