The 32 kHz reference clock on the i.MX6UL(L) can be output by
setting the external signal XTALOSC_REF_CLK_32K in one of the
following ways [1]:

|----------------------------------------------------------|
| Signal              | Pad             | Mode | Direction |
|----------------------------------------------------------|
| XTALOSC_REF_CLK_32K | ENET1_RX_EN     | ALT2 | O         |
|                     | GPIO1_IO03      | ALT3 |           |
|                     | JTAG_TCK        | ALT6 |           |
|----------------------------------------------------------|
