Frequency of operation
E-clock period
Crystal frequency
External oscillator frequency
Processor control setup time
Reset input pulse width
Mode programming setup time
Mode programming hold time
Interrupt pulse width, IRQ edge-sensitive mode
Wait recovery startup time
Timer pulse width input capture pulse accumulator input
Electrical Characteristics
1. V
2. RESET is recognized during the first clock cycle it is held low. Internal circuitry then drives the pin low for four clock cycles,
t
To guarantee external reset vector
Minimum input time (can be pre-empted by internal reset)
