Dedicated TS-1000 Registers & Pins
The KSZ8893FQL provides 32 dedicated registers to support TS-1000 OAM communication in center MC and terminal
MC modes. The TS-1000 MC registers are located at 64 to 95 (0x40 to 0x5F), and provide the following functions:
PHY address configuration
Center MC and Terminal MC configuration
OAM frame selection and execution
MC loop back setup
MC loop back counters for CRC error, timeout, good packet
Remote command access
Counters for valid MC packet transmitted and received
MC (local) - status, vendor code, and model number
Link Partner (remote) - status, vendor code, and model number
The following table lists the dedicated KSZ8893FQL pins used in center MC and terminal MC modes.
Pin
Signal Name
Type
Description
9
MCHS
Ipd
10
MCCS
Ipd
Selects center MC and terminal MC modes. See “Media Converter
Modes” subsection for details.
11
PDD#
Ipu
Power Down Detect – Use by terminal MC to detect a power-down
condition or indicate a failure has occurred.
1 = Normal operation
0 = Power down detected
After detecting a high-to-low transition on this pin, the KSZ8893FQL then
sends out an “Indicate Terminal MC Condition” OAM frame with the S0
status bit set to ‘1’ to inform the center MC that a power down condition
or failure has occurred on the terminal MC side.
If this pin is implemented, PWRDN (pin 36) needs to be de-asserted
(pulled up).
17
P1FST
Opu
Drives low to indicate fault conditions (far-end fault detected, link
partner’s fiber or UTP port down), or MC loop back mode. This pin has
8mA drive and can directly drive a LED.
18
P1CRCD
Ipd
Used by terminal MC for MC loop back – strap-in pin to select:
1 = Drop OAM frames and Ethernet frames with the following errors –
CRC, undersize, oversize. Loop back Ethernet frames with only good
CRC and valid length.
0 = Drop OAM frames only. Loop back all Ethernet frames including
those with errors.
19
P1LPBM
Ipd
Used by terminal MC for MC loop back – strap-in pin to select:
1 = Perform MC loop back at PHY of port 1
0 = Perform MC loop back at MAC of port 2
See also register 11 (0x0B) bits[3:2].
34
ML_EN
Ipd
Used by terminal MC for Missing Link Indication – strap-in pin to select:
1 = Enable Missing Link feature
0 = Disable Missing Link feature
35
DIAGF
Ipd
Used by terminal MC for Diagnostic status
1 = Diagnostic fail
0 = Diagnostic normal
After detecting a change of state on this pin, the KSZ8893FQL sends out
an “Indicate Terminal MC Condition” OAM frame with the S3 status bit
set to the state of this pin to inform the center MC that a diagnostic status
change has occurred on the terminal MC side.
