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)
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)
3) MIB counter read (read “Port1 TX Drop Packets” counter)
Write to reg. 110 with 0x1d (read MIB counter selected)
Write to reg. 111 with 0x00 (trigger the read operation)
Then
Read reg. 119 (counter value 15-8)
