11 / 94 page TMS320C5x, TMS320LC5x DIGITAL SIGNAL PROCESSORS SPRS030A – APRIL 1995 – REVISED APRIL 1996 11 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 Pin Functions for Devices in the PZ Package (Continued) SIGNAL TYPE DESCRIPTION TDM SERIAL PORT INTERFACE TDR I TDM serial receive-data input TDX O/Z TDM serial transmit-data output. In high-impedance state when not transmitting TCLKR I TDM serial receive-data clock input TCLKX I/O/Z TDM serial transmit-data clock. Internal or external source TFSR / TADD I/O/Z TDM serial receive-frame-synchronization input. In the TDM mode, TFSR / TADD is used to output / input the address of the port TFSX / TFRM I TDM serial transmit-frame-synchronization signal. Internal or external source. In the TDM mode, TFSX / TFRM becomes TFRM, the TDM frame sync. EMULATION/JTAG INTERFACE TDI I JTAG-test-port scan data input TDO O/Z JTAG-test-port scan data output TMS I JTAG-test-port mode select input TCK I JTAG-port clock input TRST I JTAG-port reset (with pull-down resistor). Disables JTAG when low EMU0 I/O/Z Emulation control 0. Reserved for emulation use EMU1 / OFF I/O/Z Emulation control 1. Puts outputs in high-impedance state when low CLOCK GENERATION AND CONTROL (SEE NOTE 2) X1 O Oscillator output X2 / CLKIN I Clock/oscillator input (PLL clock input for ’C56) CLKIN2 I Clock input (PLL clock input for ’C50, ’C51, ’C52, ’C53, ’C53S) CLKMD1, CLKMD2, CLKMD3 I Clock-mode select inputs CLKOUT1 O/Z Device system-clock output POWER SUPPLY CONNECTIONS VDDA S Supply connection, address-bus output VDDD S Supply connection, data-bus output VDDC S Supply connection, control output VDDI S Supply connection, internal logic VSSA S Supply connection, address-bus output VSSD S Supply connection, data-bus output VSSC S Supply connection, control output VSSI S Supply connection, internal logic LEGEND: I = Input O = Output S = Supply Z = High impedance NOTE 2: CLKIN2 pin is replaced by CLKMD3 pin on ’LC56 devices. |
