When using board nRF6310 these definitions will be used to define the output pins:

• SDM_GPIO_0 - pin 8
• SDM_GPIO_1 - pin 9
• SDM_GPIO_START - 8 (first pin to configure as output)
• SDM_GPIO_STOP - 9 (last pin to configure as output)

When using board PCA10003 these definitions will be used to define the output pins:

• SDM_GPIO_0 - pin 18
• SDM_GPIO_1 - pin 19
• SDM_GPIO_START - 18 (first pin to configure as output)
• SDM_GPIO_STOP - 19 (last pin to configure as output)
