4.4.4 TIM Global bus interface to the I/O registers

This address space occupies global bus addresses in the following region:
0xC000 0000 to 0xC0FF FFFF.
Individual I/O register addresses are detailed in the following table:

4.4.5 TIM Global bus interface to the VME bus master

This address space occupies global bus addresses in the following region:
0xC100 0000 to 0xC13F FFFF.
A global bus cycle in this address space causes a corresponding VME bus cycle. The VME
master takes the global bus address and shifts it left 2 bits to create a byte address. Bits 23-2
of this byte address are mapped directly to the VME bus address. It then takes the 8 bit VME
high address in Control register 4 to generate VME address bits 31-24, and the VME A1 bit in
Control register 4 is mapped to VME bus address A1. The following table details this process:
