MICROPROCESSOR INSTRUCTION REFERENCE->ACALL
ACALL Absolute Call within 2K Byte Page
Assembler Mnemonic: ACALL <addr11>
ACALL unconditionally calls a subroutine located at address <addr11>.
Only the 11 low order bits of <addr11> are used. The other bits are taken from the program counter (PC) after it has been incremented by 2 to point at the instruction following ACALL. <addr11> must therefore be within the same 2k block of memory as the first byte of the instruction following the ACALL instruction.
An error is generated if <address> is out of range.
