5. Peripheral Architecture
5.1 Registers and Interrupts
The IA80C152 combines the register set of the 8051BH and additional SFRs for the DMA and
GSC functions. Likewise, the IA80C152 combines the interrupts of the 8051BH and the
interrupts required by the DMA and GSC. Tables 11 and 12 list the IA80C152 registers
interrupts, respectively.
