STR720 - PIN DATA

21/401

4.10 Port 7 pins

Port 7 is a configurable 8/16-bit data port shared between the External Memory Interface for

the connection of memory components - such as ROM, FLASH or SRAM devices - and the

IDE interface. Both EMI and IDE are under ARM720 control through configuration registers.

Shared port lines can be selected by software using the related GCR register bit.
