TMS320F280045: Problem about the SDFM-1 Clock Input of 64 pin TMS320F280045

Junzhong Xu
Prodigy 10 points
Part Number: TMS320F280045

In the datasheet, it is said there are 3 SDFM channels, but only two GPIO can be defined as  SDFM Clock Input （SD1_C1 and SD1_C3).

So if we want to use the third SDFM channel, how to define SD1_C2 or SD1_C4? There is no Pin defined in the datasheet.

    Hi Junzhong Xu,

    The 64 pin variant of TMS320F280045 has 2 SDFM clock inputs(C1 and C3) which can only be brought out on the GPIO pins.

    Please use 100pin variant of the same(TMS320F280045PZ) to get all 4 clock inputs on the GPIOs.

    Thanks & Regards
