CY7C68053 pushes the program counter onto its stack then jumps to If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP address 0x0043, where it expects to find a ‘jump’ instruction to register), the FX2LP18 substitutes its INT2VEC byte. the USB interrupt service routine. Therefore, if the high byte (‘page’) of a jump-table address is preloaded at location 0x0044, the automatically-inserted The FX2LP18 jump instruction is encoded as shown in INT2VEC byte at 0x0045 directs the jump to the corre
