2.3 I/O Buffer Types

This section lists the types of some particular I/Os used in the HDMP-3001 chip.

Table 8. Buffer types

Buffer Type

I/O Name

Comment

O/D

APS_INTB

Need external P/U

Output

P_RXD_M_TXD[0]

Controlled by the “Isolate MII” register bit

Output

P_RXD_M_TXD[1]
P_RXD_M_TXD[2]
P_RXD_M_TXD[3]
P_RX_DV_M_TX_EN
P_RX_ER_M_TX_ER

INT

See INT Pin Configuration Section

RDYB

Uses a T/S output buffer and logically drives high before output buffer is
released or tristated

Input

TMS, TRSTB, TDI

w/
Internal P/U

P_TX_CLK_M_RX_CLK

P_RX_CLK_M_TX_CLK

SDA

P/U can be disabled if there is an external P/U

SCL

GPIO [15:0]

Note:
All of the internal P/Us are normally enabled, and they can be disabled through the JTAG port, with the exception of SCL and SDA.
The pullups on these two pins can be disabled using controls from register 0x003 bits [5:4].
