PC_COUNTER |
Program Counter. This field is a registered (one cycle delayed) reflection of the PDSP program counter. Note that the PC is an instruction address where each instruction is a 32 bit word. This is not a byte address and to calculate the byte address just multiply the PC by 4 (PC of 2 = byte address of 0x8, or PC of 8 = byte address of 0x20). |
