Type

Description

M10COL_LOCAL*

I/O, U

10M Local Collision. Input when ChipID = 00. Active low to

indicate collision on all other ChipIds. M10COL_LOCAL#

≠

(local_collision).

M10ACTO*

O, U

Output to ChipID = 00 for ChipID

≠ 00 to signal local activity.

(Refer to next 3 signals).

M10ACTI_0*

(M10ACTO*)

I,U

Connected from ChipID = 00 from ChipID

= 01 M10ACTO* to

sense activities. Open on all other ChipIDs.

M10ACTI_1*

I,U

Connected from ChipID 00 to ChipID 10 M10ACTO* to sense

activities. Open on all other ChipIDs.

M10ACTI_2*

I,U

Connected from ChipID 00 to ChipID 11 M10ACTO* to sense

activities. Open on all other ChipIDs.

M10COL_SYS*

I/O,U

ChipID 00 drives this pin the same as 10COLBP* to indicate

system collision.

M10CRS_SYS*

I/O,U

ChipID 00 drives this pin the same as 10CRSBP* to indicate

system activity.

MS10D

I/O,D

Multiple/Stacked Data Group. Transmit and receive data in

10BASE-T for multiple devices. Data is sampled at the rising

edge of MS10D_CLK and driven out on falling edge of

MS10D_CLK.

MS10D_EN*

I/O,U

Multiple/Stacked Data Enable. Active when data is valid.

MS10D_CLK

I/O, U,

Multiple/Stacked Data Clock. The bi-directional non-continuous

10 MHz recovered clock for synchronizing with MS10D and

MS10D_EN*.
