6.5.8.1 Reserved—Bits 15–8

This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

6.5.8.2 GPIOC6 (C6)—Bit 7

This bit selects the alternate function for GPIOC6.

• 0 = TC0 (default)

• 1 = TXD0

6.5.8.3 GPIOC5 (C5)—Bit 6

This bit selects the alternate function for GPIOC5.

• 0 = TC1 (default)

•1 = RXD0

6.5.8.4 GPIOB1 (B1)—Bit 5

This bit selects the alternate function for GPIOB1.

• 0 = MISO0 (default)

•1 = RXD1
