Table 11-1. Global and Test Register Address Map
Each port has a relative address range of 040h to 1FFh. The lower 000h to 03Fh address range is used for global,
test and reserved registers. The following table is a map of the registers for each port. The address offset is from
the start of each port range of 000h, 200h, 400h, and 600h. In a DS3183, writes to registers in port 4 will be
ignored and reads from port 4 registers will read back zero values. Similarly, in a DS3181, writes to registers in port
2 will be ignored and reads from port 2 will read back zero values.
Note: The RDY signal will not go active if the user attempts to read or write unused ports or unused registers not
assigned to any design blocks. The RDY signal will go active if the user writes or reads reserved registers or
unused registers within design blocks.
