The IP10[5:3] field in Peripheral Function Select Register 10 has a width of 3 bits, i.e. it allows programming one out of 8 different configurations. However, 9 values are provided instead of 8, overflowing into the subsequent field in the register, and thus breaking the configuration of the latter. Fix this by dropping a bogus zero value.
