kkkk
Description:
Subroutine call. First, return
address (PC+1) is pushed onto the
stack. The eight bit immediate
address is loaded into PC bits
<7:0>. The upper bits PC<10:9>
are loaded from STATUS<6:5>,
PC<8> is cleared. CALL is a two
cycle instruction.

Example:
HERE
CALL
THERE
Before Instruction
PC =
address (HERE)
After Instruction
PC =
address (THERE)
TOS =
address (HERE + 1)
