System Overview
3.11.2 Memory System Controller (MSC)
The Memory System Controller (MSC) is the program memory unit of the microcontroller. The flash memory is readable and writable
from both the Cortex-M and DMA. The flash memory is divided into two blocks; the main block and the information block. Program code
is normally written to the main block, whereas the information block is available for special user data and flash lock bits. There is also a
read-only page in the information block containing system and device calibration data. Read and write operations are supported in en-
ergy modes EM0 Active and EM1 Sleep.
3.11.3 Linked Direct Memory Access Controller (LDMA)
The Linked Direct Memory Access (LDMA) controller allows the system to perform memory operations independently of software. This
reduces both energy consumption and software workload. The LDMA allows operations to be linked together and staged, enabling so-
phisticated operations to be implemented.
