The registers listed below are all 16 bit registers and must be accessed with 16 bit reads and writes. This register block appears at base address 0x80004000. For example, to identify the TS-4700:
peekpoke 16 0x80004000
This will return 0x4700 to read back the model ID.
Many of the syscon options can be manipulated using ts4700ctl.
