This got lost in the update. Note that the GPU endianness is not necessarily the same as the CPU's.

Clarify type information.

It is possible for multiple register (sequential) IDs to correspond to the same register. This is done to leverage the consecutive writing mode for [[GPU Commands]], which makes it possible for a single command to write data to multiple sequential register IDs. For example, register IDs 02C1 through 02C8 all correspond to [[#GPUREG_VSH_FLOATUNIFORM_DATA|GPUREG_VSH_FLOATUNIFORM_DATA]] so that a consecutively writing command based at 02C0 will write its first parameter to [[#GPUREG_VSH_FLOATUNIFORM_CONFIG|GPUREG_VSH_FLOATUNIFORM_CONFIG]] and ever subsequent ones to [[#GPUREG_VSH_FLOATUNIFORM_DATA|GPUREG_VSH_FLOATUNIFORM_DATA]]

Writing to this register seems to signal the GPU to stop processing GPU commands from the current buffer; any command following a write to this register will be ignored. The value written to this register does not appear to matter, although 0x12345678 is the value typically written by commercial software.
