7.6.21 Counter Management Register
Name: CMR
Reset Val: 0x0000_0000
Block: CTL
Address: 0x16C
Bits
Type
Default
Description
31:3
X
Reserved
2
RW
Freeze
When this bit is set, the values of the counters are frozen until the bit is
cleared. Countable events that occur while this bit is set are stored in a
FIFO and processed after the bit is cleared such that no counts are lost.
If the FIFO fills before the Freeze bit is cleared then the bit is
automatically cleared and the counters updated.
1
W
Clear Receive
When a 1 is written to this bit then all receive counters are automatically
cleared.
0
W
Clear Transmit
When a 1 is written to this bit than all transmit counters are
automatically cleared.
7.6.22 Snoop Control Register
Name: SNCR
