Examples:
1.
MIB Counter Read (Read port 1 “Rx64Octets” Counter)
Write to reg. 121 (0x79) with 0x1c
// Read MIB counters selected
Write to reg. 122 (0x7A) with 0x0e
// Trigger the read operation
Then,
Read reg. 128 (0x80), overflow bit [31]
// If bit 31 = 1, there was a counter overflow valid
bit [30] // If bit 30 = 0, restart (reread) from this register counter bits [29:24]
Read reg. 129 (0x81), counter bits [23:16]
Read reg. 130 (0x82), counter bits [15:8]
Read reg. 131 (0x83), counter bits [7:0]
2.
MIB Counter Read (Read port 2 “Rx64Octets” Counter)
Write to reg. 121 (0x79) with 0x1c
// Read MIB counter selected
Write to reg. 122 (0x7A) with 0x2e
// Trigger the read operation
Then,
Read reg. 128 (0x80), overflow bit [31]
// If bit 31 = 1, there was a counter overflow valid
bit [30] // If bit 30 = 0, restart (reread) from this register counter bits [29:24]
Read reg. 129 (0x81), counter bits [23:16]
Read reg. 130 (0x82), counter bits [15:8]
Read reg. 131 (0x83), counter bits [7:0]
