Timing Chart of Interrupt Acceptance and Interrupt Return Instruction
Interrupt source sampled at last cycle of the command. When sampling interrupt source, it is decided to low 8-bit of
interrupt vector. M8051W core makes interrupt acknowledge at first cycle of command, executes long call to jump
interrupt routine as INT_VEC.
