I'm a bit confused using solution advisor with K2x series microcontrollers. It reports that K21/K22 do not support pin muxing. This excludes these microcontrollers and keeps only K20 in the possible solutions when you select more complicate peripheral set(for example when you select FlexBus + SDHC, 3 x UART , 2 x SPI & other peripherals).
But due to reference manuals K21/K22 in 144+ pin package supports pin muxing, so normally they has the same functionality like K20.
Is it a problem in solution advisor, reference manual error or I'm wrong?
