to enable the pull resistors in the pads. On negation of reset, based on which functionality is selected for
the signals, this signal is set to disable the pull resistors, or is continued to be held in its reset state to
indicate that the pulls are disabled only when the output driver is enabled.
2.6.4.4
The MIOS14 and the TPU signals have selectable pull-up or pull-down devices. The devices are controlled
by the PULL_SEL signal. A high on the PULL_SEL signal enables pull-up devices on the MIOS14 and
TPU signals. A low enables pull-down devices. Note that the pull devices can be disabled by the
PULL_DIS0 (MIOS14) and PRDS (TPU) bits in the PDMCR register. See

weak pull-down, PU2.6 refers to a weak pull-up to 2.6 V, and PU5 refers to a weak pull-up to 5 V. All
control of the weak-pull devices is in the pad module configuration register, described in

2.6-V inputs are 5-V tolerant, but 2.6-V outputs are not. Do not connect
2.6-V outputs to a driver or pull-up greater than 3.1 V.
Depending on the application, pins may require a pull-down resistor to
avoid getting any command due to noise.
