Reserved, set to 0000b
0000: No other devices on the serial bus
0001: 1 other device on the serial bus
1101: 13 other devices on the serial bus (maximum number supported)
0: Power up mode, normal operation
1: Power down mode
Reserved, set to 0b
0: Lane Switch Mode
1: Group Switch Mode
0: Normal operation
1: Clear global alarms
0: Switch setting updated with software strobe (address 05h)
1: Switch setting updated with hardware xSel pin
Reserved, set to 0b
00: Do not squelch
01: Output logic high on squelch
10: Output logic low on squelch
11: Output EBI level (common-mode) on squelch (recommended for AC coupled outputs)
0: Selects ISC#1 as the active switch state upon a HW/SW strobe
1: Selects ISC#2 as the active switch state upon a HW/SW strobe
0: When the device is configured for HW strobe mode (address 03h, bit 3), ISC#1 becomes active
switch setting when xSEL pin is H, ISC#2 becomes the active switch setting when xSEL pin is L
1: When the device is configured for HW strobe mode (address 03h, bit 3), A transition from H to L on
xSEL pin updates the active switch setting (ISC#1 or ISC#2 as determined by bit 7 of address 05h)
000000: Normal operation
010101: When the device is configured for SW strobe mode (address 03h, bit 3), Software strobe to
update the active switch setting (ISC#1 or ISC#2 as determined by bit 7 of address 05h)
