Pin assignments
5 The pad type is indicated by one or more of the following abbreviations: A–analog, F—fast speed, H–high voltage, I—input-only,
M–medium speed, S–slow speed. For example, pad type SH designates a slow high-voltage pad.
6 The Status During Reset pin is sampled after the internal POR is negated. Prior to exiting POR, the signal has a high
impedance. The terminology used in this column is: O – output, I – input, Up – weak pull up enabled, Down – weak pulldown
enabled, Low – output driven low, High – output driven high. A dash on the left side of the slash denotes that both the input and
output buffers for the pin are off. A dash on the right side of the slash denotes that there is no weak pull up/down enabled on
the pin. The signal name to the left or right of the slash indicates the pin is enabled.
7 The Function After Reset of a GPI function is general purpose input. A dash on the left side of the slash denotes that both the
input and output buffers for the pin are off. A dash on the right side of the slash denotes that there is no weak pull up/down
enabled on the pin.
8 Pullup is enabled only when JCOMP is negated.
9 Tie to VSS for normal operation.
