9.3. MULTI output

The MULTI pin outputs the internal analog signal to the outside of the chip for sampling the MCU. The

selectable MULTI sampling signals include NTC, VBAT, IVOL, IVOR, and IBAT, which are selected by the I2C

register. After the MULTI mode is enabled, the ratio of output parameters is shown in Table 6. If the sampled

data is too small, enlarge the gain of the MULTI. Refer to register <0x02>MULTI_CFG for detailed

information.
