Detailed Description

Overview

The Scratchpad Memory Library allows full configuration of the MSPM0 Scratchpad Memory within the LFSS IP.

The LFSS scratch pad memory is a 16- to 128-byte register based memory, which will retain data similar to a non-volatile memory as long as VBAT is supplied. The number of implemented bytes shall be configurable in a granularity of 4 bytes. This means the scratch pad memory retains data when the main VDD supply is lost or during the SHUTDOWN mode. However, the memory content won’t be retained, when the VBAT domain itself is lost.
