BR21

• Series: AC692N
• CPU Core: pi32
• SRAM: 128k in total:
  • 64k of RAM0
  • 64k of “non-volatile” RAM1
  • first 256 bytes of RAM0 are used for the interrupt vector table
  • last 16k of RAM1 are reseved for the icache (and so are inaccessible when running off flash)
• MaskROM: 10k
  • here’s the dump
• Additional info
  • I/O function map
  • IRQ map
