2C BUS START-UP PROCEDURE
Just after power-on, TB1274BFG starts tuning automatically. Initially, I2C-BUS decoder works, and then
H-VCO alignment circuit works. The following figure describes the start-up status. While Vcc is lower than
3.4V, Power-On-Reset flag indicates 1. To make TB1274BFG functioning properly, verify that POR bit is 0 by
reading the I2C BUS status data before writing data. POR is released by reading status data. Please refer the
following figure and optimize the software on the set.
1.
Power on the device.
2.
Read the I2C BUS status bytes until POR bit indicates 0.
3.
Write all bytes.
