Microcontroller-Specific Macros
Most source code standard C-language. main exception macros access special-function registers, special-function bits defined P80C652. complete macros defined P80C652 contained file REG652.H (see listing beginning page 10). shown Table there several user-definable pins assigned special EVM. These named ports sections header file. these user-definable pins, only SW2, SW3, T6RESET used this program. used read corresponding DIP-switches, T6RESET provides software reset TVP6000 video encoder. Many P80C652-specific special-function registers used control on-chip general-purpose timer interface. These localized TIMER source code. P80C652 provides bytes on-chip RAM, direct support external data memory (xdata space), read-only memory (code space). keywords xdata code sometimes required variable declarations specify type memory storage. example, arrays unsigned char, which hold TVP5020 microcode modules, declared with code keyword that they stored flash memory.
