(2) MIB counter read (read port 2 rx 64 counter)
Write to Register 110 with 0x1c
(read MIB counter selected)
Write to Register 111 with 0x2e
(trigger the read operation )
Then
Read Register 117 (counter value 31-24)
// If bit 31 = 1, there was a counter overflow
// If bit 30 = 0, restart (reread) from this register
Read Register 118 (counter value 23-16)
Read Register 119 (counter value 15-8)
Read Register 120 (counter value 7-0)
(3) MIB counter read (read port 1 tx drop packets)
Write to Register 110 with 0x1d
Write to Register 111 with 0x00
Then
Read Register 119 (counter value 15-8)
Read Register 120 (counter value 7-0)
Note:
To read out all the counters, the best performance over the SPI bus is (160+3) × 8 × 200 = 260ms, where there are 160 registers, 3 overhead, 8 clocks per
access, at 5MHz. In the heaviest condition, the byte counter will overflow in 2 minutes. It is recommended that the software read all the counters at least
every 30 seconds. The per port MIB counters are designed as “read clear.” A per port MIB counter will be cleared after it is accessed. All port dropped
packet MIB counters are not cleared after they are accessed. The application needs to keep track of overflow and valid conditions on these counters.
