All other features for devices in the PIC18FXX8 family,
including the serial communications modules, are
identical. These are summarized in Table 1-1.
Block diagrams of the PIC18F2X8 and PIC18F4X8
devices are provided in Figure 1-1 and Figure 1-2,
respectively. The pinouts for these device families are
listed in Table 1-2.
