LCALL allows an unconditional subrou-
tine call to anywhere within the 64K
program memory space.
First, the return address (PC + 1) is
pushed onto the stack. A 16-bit desti-
nation address is then loaded into the
program counter. The lower 8-bits of
the destination address are embedded
in the instruction. The upper 8-bits of
PC are loaded from PC high holding
latch, PCLATH.
