These read/write bits are software programmable. Data direction of
each port E pin is under the control of the corresponding bit in data
direction register E. Reset has no effect on port D data.
The T2CH1 and T2CH0 pins are the TIM2 input capture/output
compare pins. The edge/level select bits, ELSxB:ELSxA, determine
whether the PTE0/T2CH0 and PTE1/T2CH1 pins are timer channel
I/O pins or general-purpose I/O pins. See
