Description

After switching RSELx bits (located in register BCSCTL1) from a value of >13 to a value of <12 OR from a value of <12 to a value of >13, the resulting clock delivered by the. DCO can stop before the new clock frequency is applied. This dead time is approximately 20 us. In some instances, the DCO may completely stop, RO vs fRO Average Current ( MSP430G2553 , 3.3 V, fRO Measurement Clock = 8 MHz, One Button) . 23. 20. fRO Average Current for Various Measurement Clock Rates ( MSP430G2553 , One Button, 50 Hz) . 23. 21.

Supported by a user interface for OLED display and MP3 playback/record application. APIs. Capacitive touch scroll wheel, proximity. ABSTRACT. This application note describes how to communicate with the bq76940 family devices over I2C. The code is based on the TI MSP430G2553 . The code shows how to write the CRC function which is used to verify the transaction integrity over the I2C and how to initialize the I2C engine of the G2553 and bq76940.
