In-Circuit Serial Programming
(ICSP)
PIC18F47J53 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.
28.8
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 28-4 lists the resources required by the
background debugger.
