CRX14

Addresses above Location 06h

In IÂ²C Write mode, when the CRX14 receives the

8-bit register address, and the address is above lo-

cation 06h, the device does not acknowledge

(NoACK) and deselects itself from the bus. The

Serial Data line, SDA, stays at logic â1â (pull-up re-

sistor), and the IÂ²C Host receives a NoACK during

the 9th bit time. The SDA line stays High until the

STOP condition is issued.

In the IÂ²C Current and Random Address Read

modes, when the CRX14 receives the 8-bit regis-

ter address, and the address is above location

06h, the device does not acknowledge the Device

Select Code after the START condition, and dese-

lects itself from the bus.
