Non-removable Port Strap Option
If this strap is enabled by package and configuration settings (see
this pin will be sampled (in conjunction with LOCAL_PWR / SUSP_IND /
NON_REM[0]) at RESET_N negation to determine if ports [7:1] contain
permanently attached (non-removable) devices:
NON_REM[1:0] = ‘00’, All ports are removable.
NON_REM[1:0] = ‘01’, Port 1 is non-removable.
NON_REM[1:0] = ‘10’, Ports 1 & 2 are non-removable.
NON_REM[1:0] = ‘11’, When available, ports 1 2 & 3 are non-removable.
RESET Input
The system can reset the chip by driving this input low. The minimum active
low pulse is 1 μs.
Serial Clock (SCL)
System Management Bus Clock (SMBCLK)
Configuration Select: The logic state of this multifunction pin is internally
latched on the rising edge of RESET_N (RESET_N negation), and will
determine the hub configuration method as described in
Configuration
Hi-Speed Upstream Port Indicator
HS_IND: Hi-speed Indicator for upstream port connection speed.
The active state of the LED will be determined as follows:
CFG_SEL[1] = ‘0’,
HS_IND is active high,
CFG_SEL[1] = ‘1’,
HS_IND is active low,
‘Asserted’ = the hub is connected at HS
‘Negated’ = the hub is connected at FS
Configuration Programming Select
CFG_SEL[1]: The logic state of this pin is internally latched on the rising edge
of RESET_N (RESET_N negation), and will determine the hub configuration
method as described in
Configuration Programming Select
The logic state of this pin is internally latched on the rising edge of RESET_N
(RESET_N negation), and will determine the hub configuration method as
described in
pin is unavailable, then the logic is internally tied to ‘0’.
