50 / 306 page ![]() TMS320DM6437 Digital Media Processor SPRS345D – NOVEMBER 2006 – REVISED JUNE 2008 www.ti.com Table 2-18. Host-Port Interface Terminal Functions (continued) SIGNAL TYPE(1) OTHER(2)(3) DESCRIPTION ZWT ZDU NAME NO. NO. HDS1/MRXD1/ IPU This pin is multiplexed between HPI, EMAC, PCI, and GPIO. B2 B3 I/O/Z AD7/GP[79] DVDD33 In HPI mode, this pin is host data strobe input 1 HDS1 (I). This pin is multiplexed between HPI, EMAC, PCI, and GPIO. HRDY/MRXD2/ IPU D2 C3 I/O/Z In HPI mode, this pin is host ready output from DSP to host PCBE0/GP[80] DVDD33 (O/Z). This pin is multiplexed between HPI, MDIO, PCI, and GPIO. HCS/MDCLK/ IPU C1 D1 I/O/Z In HPI mode, this pin is HPI active low chip select input HCS AD5/GP[81] DVDD33 (I). HINT/RXD3/ IPU This pin is multiplexed between HPI, EMAC, PCI, and GPIO. C2 D2 I/O/Z AD6/GP[82] DVDD33 In HPI mode, this pin is host interrupt output HINT (O/Z). This pin is multiplexed between HPI, MDIO, PCI, and GPIO. HAS/MDIO/ IPU In HPI mode, this pin is host address strobe HAS (I). D1 C1 I/O/Z AD3/GP[83] DVDD33 For proper HPI operation, if this pin is routed out, it must be pulled up via an external resistor.
