• Description: Eprom/rom 8-bit Turbo Microcontrollers
• Manufacturer: CORERIVER Semiconductor

MiDAS1.1 Family
machine cycles to complete the IE, IP, EIE, EIP, IPH or EXIF access, 4 machine cycles to complete the
instruction and 4 machine cycles to complete the hardware LCALL to the interrupt vector location.
Thus in a single-interrupt system, the interrupt response time will always be more than 5 machine
cycles and not more than 11 machine cycles. The maximum latency of 11 machine cycle is 44 clock
cycles. Note that in the standard 80C52, the maximum latency is 8 machine cycles which equals 96
clock cycles. This is more than 50% reduction in terms of clock periods.
