4.2 Signal Descriptions
Table 4-1 describes the signals. With the exception of the JTAG pins, the GPIO function is the default at reset, unless otherwise mentioned. The peripheral signals that are listed under them are alternate functions. Some peripheral functions may not be available in all devices. See Table 3-1 for details. Inputs are not 5-V tolerant. All GPIO pins are I/O/Z and have an internal pullup (PU), which can be selectively enabled or disabled on a per-pin basis. This feature only applies to the GPIO pins. The pullups on the PWM pins are not enabled at reset. The pullups on other GPIO pins are enabled upon reset. The AIO pins do not have an internal pullup.
*******************************************
I did not understood. Only GPIO has PullUp resistors but PWM have also?
Can anyone clarify this, please?
Thanks
