data[1] = Pin output state (actual behavior depends on drive mode):

0 = Output set to low

1-99 = Output duty cycle percentage (100 Hz nominal)

100 = Output set to high

101-255 = invalid

data[2] = Pin function select and drive mode (optional, 0-15 valid)

---- FDDD

|||| ||||-- DDD = Drive Mode (based on output state of 1 or 0)

|||| |

=======================================================

|||| |

000: 1=Fast, Strong Drive Up, 0=Resistive Pull Down

|||| |

001: 1=Fast, Strong Drive Up, 0=Fast, Strong Drive Down

|||| |

010: Hi-Z, use for input

|||| |

011: 1=Resistive Pull Up,

0=Fast, Strong Drive Down

|||| |

100: 1=Slow, Strong Drive Up, 0=Hi-Z

|||| |

101: 1=Slow, Strong Drive Up, 0=Slow, Strong Drive Down

|||| |

110: reserved, do not use

|||| |

111: 1=Hi-Z,

0=Slow, Strong Drive Down

|||| |

|||| |----- F = Function

||||

=======================================================

||||

0: Port unused for GPIO. It will take on the default

||||

function such as ATX, DOW or unused. The user is

||||

responsible for setting the drive to the correct

||||

value in order for the default function to work

||||

correctly.

||||

1: Port used for GPIO under user control. The user is

||||

responsible for setting the drive to the correct

||||

value in order for the desired GPIO mode to work

||||

correctly.

||||------- reserved, must be 0

The return packet will be:

type = 0x40 | 0x22 = 0x62 = 9810

data_length = 0

35 (0x23): Read GPIO Pin Levels and Configuration State

Please see command 34 (0x22): Set or Set and Configure GPIO Pins (Pg. 58) for details on the GPIO architecture.

type: 0x23 = 3510

data_length: 1

data[0]: index of GPIO to query

0 = GPIO[0] = J8, Pin 7

1 = GPIO[1] = J8, Pin 6 (default is ATX Host Power Sense)

2 = GPIO[2] = J8, Pin 5 (default is ATX Host Power Control)

3 = GPIO[3] = J8, Pin 4 (default is ATX Host Reset Control)

4 = GPIO[4] = J9, Pin 2 (default is DOW I/O--always has 1K

Ω hardware pull-up on

SCAB.)

5-255 = reserved

Please note: Future versions of this command on future

hardware models may accept additional values for data[0],

which would return the status of future additional GPIO

pins

The return packet will be:

type = 0x40 | 0x23 = 0x63 = 9910

data_length = 4
