Operation
28.2.3 Multi-Chip Attachment Mode
The multi-chip attachment mode (MATT) allows a 24 MHz or 32 KHz crystal clock that
is an input to the i.MX28 to be routed to the PWM output pins. In this case, the normal
PWM programming parameters (for example, PERIOD, ACTIVE, and so on) are ignored.
This mode allows for supplying and controlling the crystal clock for external application
interfaces, as shown in
