56 / 118 page  4.12 Universal Host-Port Interface (UHPI) [C6727B Only] 4.12.1 UHPI Device-Specific Information UHPI_HDS[2] UHPI_HDS[1] UHPI_HCS UHPI_HRDY Internal HSTROBE Internal HRDY TMS320C6727B, TMS320C6726B, TMS320C6722B, TMS320C6720 Floating-Point Digital Signal Processors SPRS370E – SEPTEMBER 2006 – REVISED JULY 2008 www.ti.com The C672x DSP includes a flexible universal host-port interface (UHPI) with more options than the host-port interface on the C671x DSP. The UHPI on the C672x DSP supports three major operating modes listed in Table 4-11. Table 4-11. UHPI Major Modes on C672x UHPI MAJOR MODE EXAMPLE FIGURE Multiplexed Host Address/Data Half-Word (16-Bit) Mode Figure 4-15 Multiplexed Host Address/Data Fullword (32-Bit) Mode Figure 4-16 Non-Multiplexed Host Address/Data Fullword (32-Bit) Mode Figure 4-17 In all modes, the UHPI uses three select inputs (UHPI_HCS, UHPI_HDS[2:1]) which are combined internally to produce the internal strobe signal HSTROBE. The HSTROBE strobe signal is used in the UHPI to capture incoming address and control signals on its falling edge and write data on its rising edge. The UHPI_HCS signal also gates the deassertion of the UHPI_HRDY signal externally. Figure 4-14. UHPI Strobe and Ready Interaction The two HPI control pins UHPI_HCNTL[1:0] determine the type of access that the host will perform. Note that only two of the four access types are supported in Non-Multiplexed Host Address/Data Fullword Mode. Table 4-12. HPI Access Types Selected by UHPI_HCNTL[1:0] NON- MULTIPLEXED MULTIPLEXED UHPI_HCNTL[1:0] DESCRIPTION MULTIPLEXED HALF-WORD FULLWORD FULLWORD 00 HPI Control Register (HPIC) Access Y Y Y 01 HPI Data Access (HPID) with autoincrementing address Y Y N 10 HPI Address Register (HPIA) Access Y Y N 11 HPI Data Access (HPID) without autoincrementing Y Y Y address CAUTION When performing a set of HPID with autoincrementing address accesses (UHPI_HCNTL[1:0] = '01'), the set must begin and end at a word-aligned address. In addition, all four of the UHPI_HBE[3:0] must be enabled on every access in the set. CAUTION The encoding of UHPI_CNTL[1:0] on the C672x DSP is different from HCNTL[1:0] on the C671x DSP. Modes 01 and 10 are swapped. Peripheral and Electrical Specifications 56 Submit Documentation Feedback |
