7.0 RIC2A Registers (Continued)

Page Select Register ((All pages) Address 10H)

The Page Select register performs two functions:

1. It enables switches to be made between register pages,

2. It provides status information regarding the Event Logging Interrupts.

Device Type Register (Page 0H Address 11H)

This register may be used to distinguish different revisions of RIC. It will return the value 91 H for the DP83953 RIC2A

device. It will return the value 8XH for the DP83952 RICII device, or the value 0XH for the DP83950 RIC device. Write

operations to this register have no effect upon the contents.

Lower Event Count Mask Register (Page 0H Address 12H)

Note: 1 = enable, 0 = disable
