(1) Throughout this table, Master Subsystem signals are denoted by the color "blue"; Control Subsystem signals are denoted by the color
"green"; and Analog Subsystem signals are denoted by the color "orange".
(2) I = Input, O = Output, Z = High Impedance, OD = Open Drain
(3) PU = Pullup, PD = Pulldown
– GPIO_MUX1 pullups can be enabled or disabled by Cortex-M3 software (disabled on reset).
– GPIO_MUX2 pullups can be enabled or disabled by C28x software (disabled on reset).
– AIO_MUX1 and AIO_MUX2 terminals do not have pullups or pulldowns.
– All other pullups are always enabled (XRS, ARS, TMS, TDI, EMU0, EMU1).
– All pulldowns are always enabled (VREG18EN, VREG12EN, TRST).
(4) All I/Os, except for GPIO199, are glitch-free during power up and power down. See Section 3.11.
(5) This muxing option is only available on silicon Revision A devices; this muxing option is not available on silicon Revision 0 devices.
(6) Output from the Concerto ePWM is meant for the external ADC (if present).
