32 Rabbit 2000/3000 Microprocessor
Description
This instruction is used to call a subroutine. First the data in PC is pushed onto the stack. The high-order byte
of PC is pushed first, then the low-order byte. PC is then loaded with mn,16-bit address of the first instruction
of the subroutine. SP is updated to reflect the two bytes pushed onto the stack.
The Dynamic C assembler recognizes CALL label,wheremn is coded as a label.
