Description: (R) Read input from the shift registers, in hexadecimal.
Returns N+1 bytes, where N is the number of Moxtet connected
modules. The first byte is from the CPU board itself.
- Example: 101214
- 10: CPU board with SD card
- 12: 2 = PCIe module, 1 = IRQ not active
- 14: 4 = Peridot module, 1 = IRQ not active

Description: (RW) Read last written value to the shift registers, in
hexadecimal, or write values to the shift registers, also
in hexadecimal.
- Example: 0102
- 01: 01 was last written, or is to be written, to the
- first module's shift register
- 02: the same for second module
