I can’t read FlexIO registers during debugging using "EnbSys Register" window view.
I’m using KDS 3.2 & KSDK v2 and P&M SDA to evaluate FlexIO on FRDM-KL43Z board.
I wrote two PWM simple test programs, one that uses API and the other direct FlexIO register configuration (Bare-metal).
Reading FlexIO registers fails in both test it returns zero result.
As you can see at the same time reading other peripheral is O.K
Using API I have problem no output (probably configuration).
The Bare-metal program is working well I have output on PTD2 pin.
Using “not working” FlexIO display I have changed manually TIMCMP value from 0x7474 to 0x5555. The change has been accepted and PWM cycle has been changed.
Reading again this register returns again zero value.
