Eleven address bits are used address the register space. The register map is shown in Table 10-1. The
addressable range is 000h-7FFh. Register address locations are shared across the product family to preserve
software compatibility. The Serial Interface (Line) Registers are used to configure the serial port and the associated
transport protocol. The Ethernet Interface (Subscriber) registers are used to control and observe each of the
Ethernet ports. The registers associated with the MAC must be configured through indirect register write /read
access due to the architecture of the device.
When writing to a register input values for unused bits and registers (those designated with “–“) should be zero
unless specifically noted otherwise, as these bits and registers are reserved. When a register is read from, the
values of the unused bits and registers should be ignored. A latched status bit is set when an event happens and is
cleared when read.
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. The register
details are provided in the following tables.
