42 / 59 page  www.ti.com TMS320C6421 Fixed-Point Digital Signal Processor SPRS346A – JANUARY 2007 – REVISED MARCH 2007 Table 2-24. GPIO Terminal Functions SIGNAL TYPE(1) OTHER(2)(3) DESCRIPTION ZWT ZDU NAME NO. NO. GPIO 92 out of 111 GPIO pins on the C6421 device are multiplexed with other peripherals pin functions (e.g., EMAC/MDIO, McASP0, McBSP0, Timer 0, Timer 1, UART0, PWM0, PWM1, PWM2, EMIFA, and the CLKOUT0 pin), see the peripheral-specific Terminal Functions tables for the GPIO multiplexing. (1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (2) IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external pullup/pulldown resistors are required, see Section 3.2.1, Pullup/Pulldown Resistors. (3) Specifies the operating I/O supply voltage for each signal Device Overview 42 Submit Documentation Feedback |
