I2C AND SMBus SIGNALS | ||||||||||
SCL/SMBCLK | 6 | I/O | PD | I2C clock/SMBus clock. The function of this pin depends on the setting of the SMBUSz input. | ||||||
When SMBUSz = 1, this pin functions as the serial clock interface for an I2C EEPROM. | ||||||||||
When SMBUSz = 0, this pin functions as the serial clock interface for an SMBus host. | ||||||||||
This pin can be left unconnected if external interface not implemented. | ||||||||||

0 = SMBus mode selected | ||||||||||
This pin can be left unconnected if the external interface is not implemented. | ||||||||||
After reset, this signal is driven low by the TUSB4041I-Q1. Because of this behavior, TI recommends not to tie directly to supply, but instead pull up or pull down using external resistor. | ||||||||||
TEST AND MISCELLANEOUS SIGNALS | ||||||||||

1 = Automatic mode is disabled. | ||||||||||
This value is also used to set the autoEnz bit in the Battery Charging Support Register. | ||||||||||
After reset, this signal indicates the high-speed USB Suspend status of the upstream port if enabled through the Additional Feature Configuration Register. When enabled, a value of 1 indicates the connection is suspended. | ||||||||||
