Description
(1)
101
LED2-2
IPU/O
LED2 indicator 2.
Strap option for KSZ8895RQ only:
PU (default) = Select the device as clock mode in RQ SW5- RMII, 25MHz
crystal to X1/X2 pins of the device and REFCLK output 50MHz clock.
PD = Select the device as normal mode in SW5-RMII. Switch MAC5 used only.
The input clock is useless from X1/X2 pin, the device’s clock comes from
SMTXC/SMREFCLK pin, 50MHz reference clock from external 50MHz clock
source.
102
LED2-1
IPU/O
LED2 indicator 1.
Strap option for Port 3 only.
PU (default) = Enable auto-negotiation.
PD = Disable auto-negatiation.
Strap to register60 bit[7].
105
LED1-1
IPU/O
LED1 indicator 1.
Strap option for Port 3 only.
PU (default) = no force flow control, normal operation.
PD = force flow control. Strap to register50 bit[4].
106
LED1-0
IPU/O
LED1 indicator 0.
Strap option for Port 3 only.
PU (default) = force half-duplex if auto-negotiation is disabled or fails.
PD = force full-duplex if auto negotiation is disabled or fails.
Strap to register60 bit[5].
113
PS1
IPD
Serial bus configuration pin. For this case, if the EEPROM is not present, the
KSZ8895MQ/RQ/FMQ will start itself with the PS[1:0] = 00 default register
values .

TEST2
NC
NC for normal operation. Factory test pin.
Note:
1.
NC = No connect.
IPD = Input w/internal pull-down.
IPD/O = Input w/internal pull-down during reset, output pin otherwise.
IPU/O = Input w/internal pull-up during reset, output pin otherwise.
