Web100000 microsecond = 2 + 1,794 x count. Count = (100000-2)/ 1794 = 55.7402 = 56 decimal value = 38 H ( hexadecimal value) The maximum delay ( at count= ff H) is 2 + 1794 x 255 = 457,472 microsecond = 457.472 milli second = 0.45 second. When the system frequency is operating at 2 Mhz. WebDec 24, 2024 · A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1. When the computer restarts or is reset, the program counter normally reverts to 0. outsourcing aphg https://charlesupchurch.net
