9.2.12 GPIO Drive Strength Control Register (GPIOx_DRIVE)
This register can be used to explicitly set the drive strength of each output driver. If write
protection (via the SIM PROT register) is implemented on an individual device, then this
register value cannot be changed after the write protect signal is asserted.
Addresses: GPIOA_DRIVE – F140h base + Bh offset = F14Bh
9.3 Functional Description
The following block diagram illustrates the logic associated with just one of the bits in
each GPIO port. Each GPIO pin can be configured as:
