Add drive strength register to LPC43XX SCU GPIO pin configuration #34

Closed antoinevg closed 1 year ago

antoinevg commented 1 year ago

LPC43XX microcontrollers have 10 high-drive pins:

P1_17
P2_3
P2_4
P2_5
P8_0
P8_1
P8_2
PA_1
PA_2
PA_3

This PR extends the definition of the SCU pin configuration register block by adding the drive strength register at bits 9:8.
