Splet01. maj 2013 · According to the 8051 documentation, the voltage across the reset pin should be at logic high for more than 2 machine cycles (where 1 machine cycle = 4 clock cycles). So V i = 5.0 V, V f = 90 % of V i (very safe). This means V i ⋅ e − t / R C > V f ( = 0.9 V i). So e − t / R C > 0.9 so t / R C < − 1 ⋅ l n 0.9 Splet15. maj 2024 · Some processors invert the carry out and call it a borrow, I do not know off hand what the 8051 does.
