EEPROM Data Input
TS The EEPROM Data Input pin is used for output to the SPI EEPROM
memory device.
EEPROM Data Output
I
The EEPROM Data Output pin is used for input from the SPI EEPROM
memory device. The EE_DO includes an internal pull-up resistor.
EEPROM Chip Select
TS
The EEPROM Chip Select signal is used to enable the device.
EEPROM Serial Clock
TS The EEPROM Shift Clock provides the clock rate for the SPI EEPROM
interface, which is approximately 2 MHz.
FLASH Chip Enable Output.
