0050 PORT: Channel A
0051 ELECTRICAL: na since using simulator

0057
0058 Notes
0059 -----
0060 ERC32 BSP only supports single processor operations.
0061
0062 A nice feature of this BSP is that the RAM and PROM size are set in the
0063 linkcmds file and the startup code programs the Memory Configuration
0064 Register based on those sizes.
0065
0066 The Watchdog Timer is disabled.
0067
0068 This code was developed and tested entirely using the SPARC Instruction
0069 Simulator (SIS) for the ERC32. All tests were known to run correctly
0070 against sis v1.7.

0073 Memory Map
0074 ----------
0075 ```
0076 0x00000000 - 0x00000000 + _PROM_SIZE code and initialized data
0077 0x01f80000 on chip peripherals
0078 0x00000000 - 0x02000000 + _RAM_SIZE destination for initialized data
0079 BSS (i.e. unitialized data)
0080 C Heap (i.e. malloc area)
0081 RTEMS Workspace
0082
0083 The C heap is assigned all memory between the end of the BSS and the
0084 RTEMS Workspace. The size of the RTEMS Workspace is based on that
0085 specified in the application's configuration table.
