4.21.9 Data Modification Module (DMM)
The Data Modification Module (DMM) provides the capability to modify data in the entire 4 GB address
space of the RM4x devices from an external peripheral, with minimal interruption of the application.
4.21.9.1 Features
The DMM module has the following features:
Acts as a bus master, thus enabling direct writes to the 4GB address space without CPU intervention
Writes to memory locations specified in the received packet (leverages packets defined by trace mode
of the RAM trace port (RTP) module
Writes received data to consecutive addresses, which are specified by the DMM module (leverages
packets defined by direct data mode of RTP module)
Configurable port width (1, 2, 4, 8, 16 pins)
Up to 100 Mbit/s pin data rate
Unused pins configurable as GPIO pins
