The 8xC196EA is highly integrated with an enhanced peripheral set. The serial debug unit (SDU) provides
system debug and development capabilities. The SDU can set a single hardware breakpoint and provides
read and write access to code RAM through a high-speed, dedicated serial link. A stack overflow/underflow
monitor assists in code development by causing an unmaskable interrupt if the stack pointer crosses a
user-defined boundary. The 16-channel A/D converter supports an auto-scan mode that operates with no
