Overview

82C237 March 1997 CMOS High Performance Programmable DMA Controller Description The 82C237 is a modiﬁed version of the 82C37A.
The 82C237 is fully software and pin for pin compatible with the 82C37A but provides an additional mode for 16-bit DMA transfers, as well as enhanced speed.
Each channel may be individually programmed for 8-bit or 16-bit data transfers.
The 82C237 controller can improve system performance by allowing external devices to transfer data directly to or from system memory.
Memory-to-memory transfer capability is also provided, along with a memory block initialization feature.
DMA requests may be generated by either hardware or software, and each channel is independently ...
