33、n the EA pin is HIGH. 34 28 BKPT Output L Breakpoint. This pin goes active (HIGH) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are en-abled in the BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT register is HIGH, this signal pulses HIGH for eight 12-/24-/4

34、8-MHz clocks. If the BPPULSE bit is LOW, the signal re-mains HIGH until the 8051 clears the BREAK bit (by writing 1 to it) in the BREAKPT register.99 77 49 42 RESET# Input N/A Active LOW Reset.
