7 / 54 page SM320VC33, SMJ320VC33 DIGITAL SIGNAL PROCESSOR SGUS034E - FEBRUARY 2001 - REVISED OCTOBER 2002 7 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251-1443 Terminal Functions (Continued) TERMINAL TYPE† DESCRIPTION CONDITIONS WHEN NAME QTY TYPE† DESCRIPTION WHEN SIGNAL IS Z TYPE‡ TIMER SIGNALS TCLK0 1 I/O/Z Timer clock 0. As an input, TCLK0 is used by timer 0 to count external pulses. As an output, TCLK0 outputs pulses generated by timer 0. S R TCLK1 1 I/O/Z Timer clock 1. As an input, TCLK1 is used by timer 1 to count external pulses. As an output, TCLK1 outputs pulses generated by timer 1. S R SUPPLY AND OSCILLATOR SIGNALS H1 1 O/Z External H1 clock S H3 1 O/Z External H3 clock S CVDD 8 I +VDD. Dedicated 1.8-V power supply for the core CPU. All must be connected to a common supply plane.§ DVDD 16 I +VDD. Dedicated 3.3-V power supply for the I/O pins. All must be connected to a common supply plane.§ VSS 18 I Ground. All grounds must be connected to a common ground plane. PLLVDD 1 I Internally isolated PLL supply. Connect to CVDD (1.8 V) PLLVSS 1 I Internally isolated PLL ground. Connect to VSS EXTCLK 1 I External clock. Logic level compatible clock input. If the XIN/XOUT oscillator is used, tie this pin to ground. XOUT 1 O Clock out. Output from the internal-crystal oscillator. If a crystal is not used, XOUT should be left unconnected. XIN 1 I Clock in. Internal-oscillator input from a crystal. If EXTCLK is used, tie this pin to ground. CLKMD0, CLKMD1 2 I Clock mode select pins RSV0 - RSV1 2 I Reserved. Use individual pullups to DVDD. JTAG EMULATION EMU1- EMU0 2 I/O Emulation pins 0 and 1, use individual pullups to DVDD TDI 1 I Test data input TDO 1 O Test data output TCK 1 I Test clock TMS 1 I Test mode select TRST 1 I Test reset † I = input, O = output, Z = high-impedance state ‡ S = SHZ active, H = HOLD active, R = RESET active § Recommended decoupling. Four 0.1 µF for CVDD and eight 0.1 µF for DVDD. |
