General-purpose inputs/outputs (GPIOs)
The LSM6DB0 contains up to 11 GPIO pins each of which can be configured by software as
output, as input (either pull-up or pull-down), or as an alternate function in serial mode 0 or
serial mode1 (see Table 13). Each of the GPIOs can also be used as an external interrupt
source.

Memories
The LSM6DB0 has the following memory features:
– Flash memory with 0 wait states at 26.66 MHz and 2 wait states at 80 MHz
– SRAM with ECC for data and program access (read/write) referred to as RAM bank0
– SRAM for data and program access (read/write) referred to as RAM bank1
– Memory protection: the Flash and RAM memory banks cannot be read from or written
to by the JTAG link if the debug features are connected.
