Counter Interrupt Flag
The interrupt flag bit is a flag indicating the status of an interrupt. It is a
readable/writable bit. To find the status of the interrupt, you have to read
the bit value; to clear the interrupt, you have to write "1" to this bit. This
bit must first be cleared to service the next coming interrupt. Besides, you
can choose if counter 0 or counter 1 generate interrupt signal by configur-
ing "CTR0IntSet" and "CTR1IntSet" control bit.

Cascaded 32-bit Counter
You can also cascade counter 0 and counter 1 together as one 32-bit
counter/timer, and it's configured by the control bit - CTR32Set.

2.7 LAN: Ethernet Connector

The UNO-2050G is equipped with two Realtek RTL8139DL Ethernet
LAN controller that is fully compliant with IEEE 802.3u 10/100Base-T
CSMA/CD standards. The Ethernet port provides a standard RJ-45 jack
on board, and LED indicators on the front side to show its Link (Yellow
LED) and Active (Green LED) status. Please refer to A.4 for its pin
assignments.
