Section 11 Programmable Timing Pattern Controller (TPC)

11.1

Overview

The SuperH microcomputer has a built-in programmable timing pattern controller (TPC). The

TPC can provide pulse outputs by using the 16-bit integrated-timer pulse unit (ITU) as a time

base. The TPC pulse outputs are divided into 4-bit groups 3–0. These can operate simultaneously,

or independently.

11.1.1

Features

Features of the programmable timing pattern controller are listed below.

•

16-bit output data: Maximum 16-bit data can be output. TPC output can be enabled on a bit-

by-bit basis.

•

Four output groups: Output trigger signals can be selected in 4-bit groups to provide up to four

different 4-bit outputs.

•

Selectable output trigger signals: Output trigger signals can be selected by group from the

•

4-channel compare-match signals of the 16-bit integrated-timer pulse unit (ITU).

•

Non-overlap mode: A non-overlap interval can be set to come between multiple pulse outputs.

•

Can connect to DMA controller: The compare-match signals selected as output trigger signals

can activate the DMA controller for sequential output of data without CPU intervention.
