NuMicro™ NUC100 Series provides in system programming (ISP) feature to enable user to
update program memory when chip is mounted on PCB. A dedicated 4KB program memory is
used to store ISP firmware. Users can select to start program fetch from APROM or LDROM by
(CBS) in Config0.
NuMicro™ NUC100 Series provides data flash for user to store data. It is read/write through ISP
procedure. The size of each erase unit is 512 bytes. When a word will be changed, all 128 words
need to be copied to another page or SRAM in advance. For 128KB APROM device, the data
flash and application program share the same 128KB memory, if DFEN bit in Config0 is enabled,
the data flash base address is defined by DFBADR and application program memory size is (128-
0.5*N)KB and data flash size is 0.5*N KB. For 64/32KB APROM devices, data flash size is 4KB
and start address is fixed at 0x0001_F000.
