NAME

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
