Overview
14.1.1 Single-Chip Mode
In single-chip mode, signals default to GPIO inputs after a system reset. Table 14-4 is a

1
Pull-ups are not active when GPIO functions are selected for the pins.
2
The primary functionality of a pin is not necessarily its default functionality. Pins that have GPIO functionality will
default to GPIO inputs.
3
Pull-up is active only with the SYNCA function.
4
Pull-up is active only with the SYNCB function.
5
Pull-up is active only with the SDA function.
6
Pull-up is active only with SCL function.
7
Pull-up is active when JTAG_EN is driven high.
