10.2 Global Register Definitions
Note that although most registers are defined as 16-bit registers, the constituent bytes are accessed
through the parallel or SPI interfaces one byte at a time. Individual address locations are defined for each
byte.

Default
Bits 13-15: Revision Number (REV[2:0]) Contains a sequential number that is related to, but not equal to, the
device revision on the top brand. Silicon revision numbering begins at 000.
Bit 12: SPI Slave (SPIS) If this bit is set to 1, the device only supports a SPI Slave microprocessor port.
Bits 9-11: Voice Channels (VC[2:0]) This contains the number of voice channels supported.
Bit 8: VCAT (VCAT) If this bit is set to 1, the device has VCAT functionality.
Bits 3-7: Serial WAN Ports (WP[4:0]) These bits contain the number of WAN ports in the device.
Bit 3: Gigabit Ethernet Support (GBE) If this bit is set, the device support GbE.
Bits 0-1: Ethernet LAN Ports (MP[1:0]) These bits contain the number of MAC ports in the device.

*Note, the single-port DS33X11 and DS33W11 devices support reservation of the VCAT overhead byte position as
required by ITU-T G.8040, not the actual concatenation of WAN links.
