Detailed Features
5.12 eMIOS
The eMIOS module provides the functionality to generate or measure time events. A unified channel (UC)
module is employed that provides a superset of the functionality of all the MIOS channels, while providing
a consistent user interface. This allows more flexibility as each unified channel can be programmed for
different functions in different applications. In order to identify up to two timed events, each UC contains
two comparators, a time base selector and registers. This structure is able to produce match events, which
can be configured to measure or generate a waveform. Alternatively, input events can be used to capture
the time base, allowing measurement of an input signal.
5.13 eTPU
The eTPU is an enhanced co-processor designed for timing control. Operating in parallel with the host
CPU, the eTPU processes instructions and real-time input events, performs output waveform generation,
and accesses shared data without host intervention. Consequently, for each timer event, the host CPU setup
and service times are minimized or eliminated. A powerful timer subsystem is formed by combining the
eTPU with its own instruction and data RAM. High-level assembler/compiler and documentation allows
customers to develop their own functions on the eTPU.
The eTPU is an enhanced version of the TPU module implemented on the MC68332 and MPC500
products. Enhancements of the eTPU include a more powerful processor which handles high-level C code
efficiently and allows for more functionality and increased performace. Although there is no compatibility
at microcode level, the eTPU maintains several features of older TPU versions and is conceptually almost
identical. The eTPU library is a superset of the standard TPU library functions modified to take advantage
of enhancements in the eTPU. These, along with a C compiler, make it relatively easy to port older
applications. By providing source code for the Freescale library, it is possible for the eTPU to support the
users own function development.
The eTPU includes these distinctive features:
26
•
•
32 channels, each channel is associated with one input and one output signal.
— Enhanced input digital filters on the input pins for improved noise immunity.
— Identical, orthogonal channels: each channel can perform any time function. Each time
— Each channel has an event mechanism which supports single and double action functionality
— Input and output signal states visible from the host
Two independent 24-bit time bases for channel synchronization:
— First time base clocked by system clock with programmable prescale division from 2 to 512
— Both time bases can be exported to the eMIOS timer module
— Second time base counter can work as a continuous angle counter, enabling angle based
function can be assigned to more than one channel as a given time, so each signal can have
any functionality.
in various combinations. It includes two 24-bit capture registers, two 24-bit match registers,
24-bit greater-equal and equal-only comparators
(in steps of 2), or by output of second time base prescaler
applications to match angle instead of time.
