Overview
interchip digital link (IDL), physical layer protocols. This module is primarily intended to facilitate
designs that include ISDN interfaces.
1.4.2
The PWM unit is intended for use in control applications. With a suitable low-pass filter, it can be used as
a digital-to-analog converter. This module generates a synchronous series of pulses. The duty cycle of the
pulses is under software control.
Its main features include the following:
The PWM implements a simple free-running counter with a width register and comparator such that the
output is cleared when the counter exceeds the value of the width register. When the counter wraps around,
its value is not greater than the width register value, and the output is set high. With a suitable low-pass
filter, the PWM can be used as a digital-to-analog converter.
1.4.3
The QSPI module provides a serial peripheral interface with queued transfer capability. It supports up to
16 stacked transfers at a time, making CPU intervention between transfers unnecessary. Transfer RAMs
in the QSPI are indirectly accessible using address and data registers. Functionality is similar to the QSPI
portion of the QSM (queued serial module) implemented in the MC68332.
The QSPI has the following features:
1.4.4
The USB controller on the MCF5272 supports device mode data communications with a USB host
(typically a PC). One host and up to 127 attached peripherals share USB bandwidth through a
host-scheduled, token-based protocol. The USB uses a tiered star topology with a hub at the center of each
star. Each wire segment is a point-to-point connection between the host connector and a peripheral
connector.
