3.2.5. USART Interface
KE600/KE608 have two UART Drivers as follow :
- USART1 : Hardware Flow Control / SW upgrade / Calibration
- USART2 : SW debug trace.
Table 3 USART Interface Spec.
3.2.6. ADC channel
BBP ADC block is composed of 7 external ADC channel. This block operates charging process and
other related process by reading battery voltage and other analog values.
