# P9.31 GPIO3_14
setp [PRUCONF](DRIVER).stepgen.00.steppin         0x8E

The value above is given meaning by the PRU code, which uses the
kernel numbering scheme, but offset by one so that 0x00 (the default
value for all HAL signals) means don't do anything.  The details are:

GPIO Pin Value:
value = 32 * ( <GPIO_bank> + 1 ) + bit

PRU Direct Output Bits:
value = 32 * (4 + 1 ) + bit = 160 + bit = 0xA0 + bit

So 0x8E = 142 = (32 * 4) + 14 = GPIO bank 3, bit 14
