Silicon limitations

2.1

HSI RC oscillator cannot be switched off in RUN mode

Description

The HSI RC oscillator cannot be switched off in Run mode. This causes negligible extra

power consumption compared to the total consumption of the MCU in Run mode.

Workaround

No workaround available.

2.2

LSI oscillator remains ON during Active Halt mode (MVR ON)

when AWU uses HSE/Div as input clock

Description

The LSI RC oscillator is not switched off in Active Halt mode with main voltage regulator

(MVR) on, when the AWU uses high speed external clock divided by prescaler (HSE/Div)

(clock source option enabled by CKAWUSEL option bit). This causes negligible extra power

consumption compared to the total consumption of the MCU in Active Halt mode with main

voltage regulator (MVR) on.

Workaround

No workaround available.

2.3

TIM1_CH4 mapped on PC4 and PD7 ports by AFR4 option

Description

Timer 1 channel 4 (TIM1_CH4) is available both on pin PC4 and PD7 when the alternate

function remapping AFR4 option bit is set.

Workaround

No workaround available. It is recommended to only use the AFR4 Alternate function

remapping option for the 44-pin package where PC4 is not present.
