1 2.6-V outputs cannot be connected to a pull-up or driver greater than 3.1 V.
2 During reset, the output enable to the pad driver is negated and the PD is active. After reset is negated, the PD is
disabled.
3 Neither a pull-up to greater than 3.1 V or an external output that can drive greater than 3.1 V should be connected to
this pin while the 2.6-V driver is enabled.
4 5 V on mask set K85H.
5 Requires a pull-up to 2.6 V if interrupts are ever enabled for this IRQ input.
6 Pull-up/pull-down is active when pin is defined as an input and/or during reset; therefore, output enable is negated.
This also means that external pull-up/pull-down is not required unless specified.
7 Powered by KAPWR (keep-alive power supply).
8 The MODCK[1:3] are shared functions with IRQ[5:7]. If IRQ[5:7] are used as interrupts, the interrupt source should
be removed during PORESET/TRST to insure the MODCK pins are in the correct state on the rising edge of
PORESET/TRST.
9 An active negate signal that requires an external pull-up resister. On dual-voltage, type-4 pads, hysteresis is always
enabled on the 5-V input buffer. Hysteresis affects only the 2.6-V input buffers on which it is enabled.
10 PORESET only on mask set K85H.
11 5-V tolerant, even when in output mode.
12 TRST in mask set K85H.
13 A_ECK in mask set K85H.
14 Whether the Pull device is a pull-up or a pull-down is determined by the state of the PULL_SEL pin.
