Bits 15 to 14: General Purpose IO 8 Select [1:0] (GPIO8S[1:0]). These bits determine the function of the GPIO8
pin. These selections are only valid if GL.CR1.GPM[1:0] is not set to 01.
Bits 13 to 12: General Purpose IO 7 Select [1:0] (GPIO7S[1:0]). These bits determine the function of the GPIO7
pin.
Bits 11 to 10 : General Purpose IO 6 Select [1:0] (GPIO6S[1:0]). These bits determine the function of the
GPIO6 pin. These selections are only valid if GL.CR1.MEIMS=0.
Bits 9 to 8: General Purpose IO 5 Select [1:0] (GPIO5S[1:0]). These bits determine the function of the GPIO5
pin.
Bits 7 to 6: General Purpose IO 4 Select [1:0] (GPIO4S[1:0]). These bits determine the function of the GPIO4
pin. These selections are only valid if
Bits 5 to 4: General Purpose IO 3 Select [1:0] (GPIO3S[1:0]). These bits determine the function of the GPIO3
pin.
Bits 3 to 2: General Purpose IO 2 Select [1:0] (GPIO2S[1:0]). These bits determine the function of the GPIO2
pin. These selections are only valid if GL.CR2.GKROS=0.
