3. INSTRUCTIONS SET DETAILS

3.1.

ACALL *

3.1.1. LARGE

Instruction:

ACALL addr11

Function:

Absolute call

Description:

ACALL unconditionally calls a subroutine located at the indicated

address. The instruction increments the PC twice to obtain the address

of the following instruction, then pushes the 16-bit result onto the stack

(low-order byte first) and increments the stack pointer twice. The

destination address is obtained by successively concatenating the five

high-order bits of the incremented PC, opcode bits 7-5, the second byte

of the instruction. The subroutine called must therefore start within the

same 2K block of program memory as the first byte of the instruction

following ACALL. No flags are affected.
