Table 19. “All Port Dropped Packet” MIB Counters Indirect Memory Offsets
Examples:
1. MIB Counter Read (Read port 1 “Rx64Octets” Counter)
Write to reg. 110 with 0x1c (read MIB counters selected)
Write to reg. 111 with 0x0e (trigger the read operation)
Then
Read reg. 117 (counter value 30-24) // If bit 30 = 0, restart (reread) from this register
Read reg. 118 (counter value 23-16)
Read reg. 119 (counter value 15-8)
Read reg. 120 (counter value 7-0)
2. MIB Counter Read (Read Port 2 “Rx64Octets” Counter)
Write to reg. 110 with 0x1c (read MIB counter selected)
Write to reg. 111 with 0x2e (trigger the read operation)
