60 Register Description (Continued)
611 DP83950 ID 1 REGISTER (0x30)
The DP83950 ID Registers 1 and 2 are used to associate one or two DP83950’s in a multi-DP83950 repeater system with a
DP83957
The ID address which is placed in these registers must correspond to the value that is placed in the DP83950’s Address
Register These registers are located at Page 0 Address 0x17 in DP83950 Refer to Section 80 RIC Registers of the DP83950

613 OVERFLOW STATUS 1 REGISTER (0x40)
Overflow Status Registers 1 and 2 are used to indicate a Port Attribute overflow Overflow Status Register 1 must be used in
conjunction with Overflow Register 2 to determine the overflow attribute
If an overflow interrupt occurs the CPU must in the first instance read Overflow Status Register 1 to determine on which
DP83950 (ie 1 or 2) and Port number the overflow occurred Following this Overflow Register 2 needs to be read to determine
the actual Port attribute which caused the interrupt
