When asserted LOW, the P1 P2 P3 P4 internal address value of the counter will be read back on the address lines. During CNTRD operation, both CNTLD and CNTINC must be HIGH. Counter readback operation has higher priority over mask register readback operation. Counter readback operation is independent of port chip enables. If address readback operation
