Ground
1) These pads are I/O pads with input only function. Its input characteristics are identical with the input
characteristics as defined for class A pads.
2) In case of a power-fail condition (one or more power supply voltages drop below the specified voltage range),
an undefined output driving level may occur at these pins.
3) Programmed by software as either break input or break output.
4) These pads are input only pads with input characteristics.
5) Input only pads with input spike filter.
6) Open drain pad with input spike filter.
7) The dual input reset system of TC1762/TC1766ED, assumes that the PORST reset pin is used for power-on
reset only. It has to be taken into account that if a system uses the PORST reset input for other system resets,
the emulation part of the TC1766ED Emulation Device is reset as well. Thus, it will always force a complete
re-initialization of the emulator and will prevent the user debugging across these types of resets.
8) Input only pads without input spike filter.
