The MK22FN512CBP12R datasheet states:
PTB0, PTB1, PTC3, PTC4, PTD4, PTD5, PTD6, and PTD7 I/O have both high drive and normal drive capability
selected by the associated PTx_PCRn[DSE] control bit. All other GPIOs are normal drive only.
However the Ref Manual in the I2C section has register I2Cx_C2 which has a the HDRS bit to select High Drive mode.
The I2C1 bus is only availabe on pins PTC10/11 and PTCE0/1 which aren't listed as high drive GPIOs in the datasheet, but the HDRS bit appears to be available for I2C1, as well as I2C0. There isn't any note regarding the limitation of HDRS bit applicability, so can high drive be done on I2C1 for this part or is it limited to normal drive?
