Compatibility doubts about I2C SCL SDA between a Slave (STM32L0) with VDD=3V3 & a Host with VDD=1V8 , pull-up resistors on the Host side.

Dear ST Community,I do have a doubt regarding an I2C communication between my STM32L031K6Tx that is the slave and powered with VDD=3V3 and a host that is powered with 1V8. Pull-up resistors are connected to 1V8 (host side).I did a functional test and...

May someone help explain what are TIM1_CH1 or TIM1_CC1 ?

I am using the STM32F407Zg MCU and is learning how to set up the ADC for continuous sampling by timer. But I have trouble to understand the manual. The ADC section refer to TIM1_CH1 or TIM1_CC1 etc. But the Timer section do not use the same term.
