3. The input clock signal must reach the defined levels V
Figure 56. External clock drive XTAL1
When Direct Drive is selected, an external clock source can be used to drive XTAL1. The
maximum frequency of the external clock source depends on the duty cycle: When 64 MHz
is used, 50% duty cycle is granted (low phase = high phase = 7.8 ns); when for instance
32 MHz is used, a 25% duty cycle can be accepted (minimum phase, high or low, again
equal to 7.8 ns).
Memory cycle variables
The tables below use three variables which are derived from the BUSCONx registers and
represent the special characteristics of the programmed memory cycle. The following table
describes how these variables are computed.
