TM4C123GE6PM Datasheet, PDF (484/1408 Pages) Texas Instruments – Tiva™ TM4C123GE6PM Microcontroller

System Control
Register 144: Non-Volatile Memory Information (NVMSTAT), offset 0x1A0
This register is predefined by the part and can be used to verify features.
Important: This register is provided for legacy software support only.
The ROM Third-Party Software (ROMSWMAP) register should be used to determine
the presence of third-party software in the on-chip ROM on this microcontroller. A read
of the TPSW bit in this register correctly identifies the presence of legacy third-party
software. Software should use the ROMSWMAP register for software that is not on
legacy devices.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
32 Word Flash Write Buffer Available
When set, indicates that the 32 word Flash memory write buffer feature
is available.
