24 to FF <returns the register address>
The error maps are bit maps which have an error bit for each map entry:
Error map 0 has error bits for map entry 7 to 0
Error map 1 has bits 7-4 set to 0, then error bits for map entry 0xB to 8.
Both error maps must be 0 for the switch to be enabled.
The register address is set and the register value read from a single byte address.
Both the VME bus controller and either TIM1 or TIM4 can access it at these addresses:
VME I/O space address offset
= 0xDF
TIM I/O space address = 0xC0000102
