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

TS	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

Bidirectional	P_TX_CLK_M_RX_CLK
w/
w/	P_RX_CLK_M_TX_CLK
Internal P/U	P_RX_CLK_M_TX_CLK
for input	SDA	P/U can be disabled if there is an external P/U
mode	SDA	P/U can be disabled if there is an external P/U

	SCL
	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].
