| The following I/O port assignments are currently used:
Port | Name | Access type |
&2E0 | PORT_STATUS | Word read |
&2E1 | PORT_CMD | Word write |
&2E2 | PORT_DATA | Byte or word read/write |
The following sequence of operations should occur to perform an HPC call:
The port based HPC packets have the same 16384 byte limit that proper HPC
packets have.
Note that only HPC services provided by the ARMEdit module can be called
using this I/O port system; other services can only be called via the normal
HPC system. However, the HPC identifier is still checked. |
