NuMicro M058S Series Datasheet
6.4 Flash Memory Controller (FMC)
6.4.1 Overview
The M058S Series are equipped with 64/32/16/8 KB on chip embedded Flash memory for
application program (APROM) that can be updated through ISP registers. In-System-
Programming (ISP) and In-Application-Programming (IAP) enable user to update program
memory when chip is soldered on PCB. After chip power on Cortex-M0 CPU fetches code from
APROM or LDROM decided by boot select (CBS) in CONFIG0. By the way, it also provides
additional 4 KB DATA Flash for user to store some application depended data before chip power
off in 64/32/16/8 KB APROM model.
It provides more settings in CONFIG0 to support more advanced functions, including power-on
with tri-state I/O, default to enable WDT after booting, enable WDT in Power-down mode, and IAP
functions. The following table shows the added functions of M058S Series.
