Description
If Center MC sends the “Remote Command” in register 0x42h, this register
value will be used for M47-M40 of the Maintenance frame, instead of register
0x57h.
[AMM47:AMM40] = bits[7:0] of the KS8993F data byte if the Operating Mode
in register 0x4Ah bits[1:0] is set to “10”
Description
At both the Center and Terminal sides, this counter is incremented when a
valid maintenance packet is transmitted.
0000_0000 : No valid maintenance packet transmitted
0000_0001 : 1 valid maintenance packet transmitted
1111_1111 : 255 valid maintenance packets transmitted
This counter is cleared when 0x00h is written to reg. 0x44h.
Description
At both the Center and Terminal sides, this counter is incremented when a
valid maintenance packet (good CRC, valid OP code, valid direction) is
received.
0000_0000 : No valid maintenance packet received
0000_0001 : 1 valid maintenance packet received
1111_1111 : 255 valid maintenance packets received
This counter is cleared when 0x00h is written to reg. 0x44h.
Description
This register is shadow of 0x58h register when the OPT link is up.
