Note:

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 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.
