Expressions
Expressions are used in the operand field of MPASM’s source line and may
contain constants, symbols, or any combination of constants and symbols
separated by arithmetic operators. Each constant or symbol may be preceded
by a plus or minus to indicate a positive or negative expression.
Extended Microcontroller Mode
(PIC17CXXX and PIC18CXXX Devices Only)
In extended microcontroller mode, on-chip program memory as well as
external memory is available. Execution automatically switches to external if
the program memory address is greater than the internal memory space of
the PIC17CXXX or PIC18CXXX device.
External Input Line (MPLAB ICE only)
An external input signal logic probe line (TRIGIN) for setting an event based
upon external signals.
External Linkage
A function or variable has external linkage if it can be accessed from outside
the module in which it is defined.
External RAM (PIC17CXXX and PIC18CXXX Devices Only)
Off-chip Read/Write memory.
External Symbol
A symbol for an identifier which has external linkage.
External Symbol Definition
A symbol for a function or variable defined in the current module.
External Symbol Reference
A symbol which references a function or variable defined outside the current
module.
External Symbol Resolution
A process performed by the linker in which external symbol definitions from all
input modules are collected in an attempt to update all external symbol
references. Any external symbol references which do not have a
corresponding definition cause a linker error to be reported.
Note: MPASM expressions are evaluated in 32-bit integer math.
