EQEP Timing Requirements Table 7-54. EQEP Switching Characteristics NO. PARAMETER DESCRIPTION MIN MAX UNIT QEP6 td(QEP-CNTR) Delay time, external clock to counter increment 24 ns For more information, see Enhanced Quadrature Encoder Pulse (EQEP) Module section in Peripherals chapter in the device TRM. 7.10.5.9 GPIO Table 7-55, Table 7-56, and Table 7-57 present timing conditions, requirements, and switching characteristics for GPIO. For more details about features and additional description information on the device GPIO, see the corresponding subsections within Signal Descriptions and Detailed Description sections. Note The device has multiple GPIO modules. GPIOn_x is generic name used to describe a GPIO signal, where n represents the specific GPIO module and x represents one of the input/output signals associated with the module. Table 7-55.
