Subroutine Call
[ label ] CALL k

PC+ 1
k<12:8>
PC<15:13>
Subroutine call within 8K page. First,
return address (PC+1) is pushed onto
the stack. The 13-bit value is loaded into
PC bits<12:0>. Then the upper-eight
bits of the PC are copied into PCLATH.
Call is a two-cycle instruction.
See LCALL for calls outside 8K memory
space.
