are tied together through 2-kΩ resistor.

READ address and data transfer (see Figure 9)
After receiving the READ op code, the EEPROM samples the READ address on the next eight rising edges of
SCLK. The device sources the address at the falling edge of SCLK. The EEPROM then sends out a dummy
0 bit on the D/Q line, which is followed by the 16-bit data word with the MSB first. Output data changes are
triggered by the rising edges of SCLK. The data is also read by the TL16PNP100A on the rising edges of SCLK.
