operational mode functional description
When both mode pins are 1 and the test pin is 0, on the rising edge of PGOOD, the TPS2340A enters operational
mode. In this mode, the PCI hot-plug controller is able to address multiple TPS2340A ICs and multiple slots.
Input status for all slots is grouped into four channels that can be requested by the PCI hot-plug controller.
channel selection
The PCI hot-plug controller indicates to the TPS2340A which channel to read back via signaling on the SIL pin.
The SIL pin asserts low for one SIC clock to indicate a start bit, followed by three SIC clocks of channel address
information in the order of channel address LSB followed by channel address MSB and a reserved bit. So as
an example, if the hot-plug controller desires to read non-interrupt capable input data from the TPS2340A
(channel 01 binary), the SIL sequence is shown in Table 3.
