TIMING CONDITIONS
Note:
Because of space limitations, the generic
terms “PIC18FXXXX” and “PIC18LFXXXX”
are used throughout this section to refer to
the PIC18F2450/4450 and PIC18LF2450/
4450 families of devices specifically and
only those devices.
The temperature and voltages specified in Table 21-5
apply to all timing specifications unless otherwise
noted. Figure 21-4 specifies the load conditions for the
timing specifications.
