PIC18F46J50 FAMILY

27.7 In-Circuit Serial Programming

(ICSP)

PIC18F46J50 family microcontrollers can be serially

programmed while in the end application circuit. This is

simply done with two lines for clock and data, and three

other lines for power, ground and the programming

voltage. This allows customers to manufacture boards

with unprogrammed devices and then program the

microcontroller just before shipping the product. This

also allows the most recent firmware or a custom

firmware to be programmed.

27.8 In-Circuit Debugger

When the DEBUG Configuration bit is programmed to

a ‘0’, the In-Circuit Debugger functionality is enabled.

This function allows simple debugging functions when

used with MPLAB® IDE. When the microcontroller has

this feature enabled, some resources are not available

for general use.

Table 27-4 lists the resources required by the

background debugger.
