    You are looking at the wrong place in the table. We are talking about pin PTB16 (PORTB_PCR16) which is linked to UART0 with ALT3.

    3 is 0011b and 7 is 0111b. 0011b & 0111b is still 0011b (bitwise AND) and thus still 3. The 0111b is just ANDed as a bitmask to prevent users from trying to go beyond the allowed 0 to 7 range.

    It's ok to ask, but it seems rather unusual to me. Most people asking questions here have a more or less precise idea of a project which they want to realize with their Teensy, thus, these "under the...

    No JTAG, it MUST be UART. Thus, your error is before: PORT_PCR_MUX(3) sets the pin to ALT2.

    serial_begin(uint32_t divisor) is an internal helper function which initializes the UART with a clock...
