System Control
Register 122: Device Capabilities 0 (DC0), offset 0x008
This legacy register is predefined by the part and can be used to verify features.
Important: This register is provided for legacy software support only.
The Flash Size (FSIZE) and SRAM Size (SSIZE) registers should be used to determine
this microcontroller's memory sizes. A read of DC0 correctly identifies legacy memory
sizes but software must use FSIZE and SSIZE for memory sizes that are not listed
below.
