Yes, but, technically PATA is a souped-up ISA bus with address decode already done for all but the lower few bits.  Old 16-bit ISA IDE cards were often referred to as paddleboards because the only thing on the card was a small address decoder/buffer chip and the rest of the lines went virtually straight through from the ISA bus to the drive.

So saying ISA is only partially incorrect. :-)
