1.0 DEVICE OVERVIEW
This document contains device specific information for
the PIC18F010/020 microcontrollers. These devices
come in 8-pin packages. Table 1-1 is an overview of the
features. Figure 1-1 presents the block diagram for the
PIC18F010/020 devices and Table 1-2 gives the pin
descriptions.

2.5 External Clock Input
The EC oscillator mode requires an external clock
source to be connected to the OSC1 pin. The feedback
device between OSC1 and OSC2 is turned off in this
mode to save current. There is no oscillator start-up
time required after a Power-on Reset or after a recov-
ery from SLEEP mode.
In the EC oscillator mode, the oscillator frequency
divided by 4 is available on the OSC2 pin. This signal
may be used for test purposes or to synchronize other
logic. Figure 2-4 shows the pin connections for the EC
oscillator mode.
