 # 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
