49 / 171 page  Pin Assignments 49 June 2003 − Revised August 2004 SPRS222C Table 1−6. Terminal Functions (Continued) SIGNAL DESCRIPTION IPD/ IPU‡ TYPE† NAME DESCRIPTION IPD/ IPU‡ TYPE† DM640 DM641 8-BIT VIDEO PORT 0 (VP0) [DM641 AND DM640] VP0D[7] AD15 AD15 VP0D[6]/CLKR0§ AE15 AE15 VP0D[5]/FSR0§ AB16 AB16 Video port 0 (VP0) data input/output (I/O/Z) or McBSP0 data input/output (I/O/Z) [default] VP0D[4]/DR0§ AC16 AC16 I/O/Z IPD Video port 0 (VP0) data input/output (I/O/Z) or McBSP0 data input/output (I/O/Z) [default] VP0D[3]/CLKS0§ AD16 AD16 I/O/Z IPD For more details on the McBSP0 pin functions, see McBSP0 section of this VP0D[2]/DX0§ AE16 AE16 For more details on the McBSP0 pin functions, see McBSP0 section of this table and the Device Configurations section of this data sheet. VP0D[1]/FSX0§ AF16 AF16 table and the Device Configurations section of this data sheet. VP0D[0]/CLKX0§ AF17 AF17 VP0CLK1 AF12 AF12 I/O/Z IPD VP0 clock 1 (I/O/Z) VP0CLK0 AF14 AF14 I IPD VP0 clock 0 (I) VP0CTL2 AD17 AD17 VP0 control 2 (I/O/Z) VP0CTL1 AC17 AC17 I/O/Z IPD VP0 control 1 (I/O/Z) VP0CTL0 AE17 AE17 I/O/Z IPD VP0control 0 (I/O/Z) TIMER 2 — — No external pins. The timer 2 peripheral pins are not pinned out as external pins. TIMER 1 TOUT1/LENDIAN B5 B5 O/Z IPU Timer 1 output (O/Z) Boot Configuration: Device endian mode [LENDIAN] (I). Controls initialization of DSP modes at reset via pullup/pulldown resistors − Device Endian mode 0 – Big Endian 1 − Little Endian (default) For more details on LENDIAN, see the Device Configurations section of this data sheet. TINP1 A5 A5 I IPD Timer 1 or general-purpose input TIMER 0 TOUT0/MAC_EN C5 C5 O/Z IPD Timer 0 output (O/Z) Boot Configuration: MAC enable pin [MAC_EN] (I) The MAC_EN pin controls the selection (enable/disable) of the EMAC and MDIO peripherals. For more details, see the Device Configurations section of this data sheet. TINP0 A4 A4 I IPD Timer 0 or general-purpose input INTER-INTEGRATED CIRCUIT 0 (I2C0) SCL0 E4 E4 I/O/Z — I2C0 clock. SDA0 D3 D3 I/O/Z — I2C0 data. † I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground ‡ IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite supply rail, a 1-k Ω resistor should be used.) § These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet. |
