15 / 46 page  FS970X Rev. 4.4 15/46 Buzzer Generator FBP generator is controlled by ENBP. CNTBP and CMP1. The true value Chart is shown in Chart 4. ENBP CNTBP CMP1 FBP H X X 2.6 kHz L L X 0, (L) L X L 0, (L) X H H 2.6 kHz Chart 4. FBP true value Chart The output of buzzer, BZR, is an open drain output. It can be connected to an external pull-up resistor to pull the “Hi” output to the required voltage. When ENBP is “Hi” or CMP1 and CNTBP are both “Hi”, BZR will produce approx. 2.6 kHz square-wave output to initiate buzzer. ENBP and CNTBP can be set up directly by digital interface while the value of CMP1 is related to the measurement status. Please refer to Function Network for details. When ENOSCO_=0, the square-wave output of OSCO is fixed to be 2.000 MHz. When ENOSCO_=1,the fixed output is 0. This will save VCC power consumption. |
