OUTPUT 1 OUTPUT 0

Bits 1 - 0: General Purpose Outputs to Transition Module (Read/Write)

0 = set output line to 0

1 = set output line to 1

Bit 2: Transition Module USB Power Enable (Read Only)

0 = RTM USB power is Off

1 = RTM USB power is On

Bit 3: Reserved

Bits 5 - 4: General Purpose Inputs from Transition Module (Read Only)

0 = input line is at 0

1 = input line is at 1

Bit 6: Fan Sensor Status from Transition Module (Read Only)

0 = input line is at 0

1 = input line is at 1

Bit 7: Ext Reset Status from Transition Module (Read Only)

0 = input line is at 0

1 = input line is at 1

NOTE: A multiplexed serial I/O scheme is used to connect these register bits to the I/O

pins on the Transition Module. Because of this, there is an output latency of 80µs and the

maximum input frequency (to avoid losing input transitions) is approximately 6.2 kHz.
