GENERAL DESCRIPTION
TSA5518M Control data is entered via the I2C-bus; five serial bytes are required to address the device, select the oscillator frequency, program the 7 output ports and set the charge-pump current. Digital information concerning this port can be read out of the SDA line (one status byte) during a READ operation. A flag is set when the loop is ‘in-lock’ and is read during a READ operation.
