Notes:
Signal names are based on configured functionality. Most connections supply a single signal. Some connections
provide a signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is
deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are
shown with and without overbars, such as HAS/HAS. Some connections have two or more configurable functions;
names assigned to these connections indicate the function for a specific configuration. For example, connection N2
is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7
when the GPIO function is enabled for this pin. Unlike in the TQFP package, most of the GND pins are connected
internally in the center of the connection array and act as heat sink for the chip. Therefore, except for GNDP and
GNDP1 that support the PLL, other GND signals do not support individual subsystems in the chip.
