STM32G030J6M6, SPI

Hello.Is it possible to use hardware SPI with  STM32G030J6M6 (SO-8)?SPI1 use PA1 (NRST pin) for CLK without remap possibility.SPI2 also use PA1 (NRST pin) for CLK, but has CLK remap to PC14. In that case no MOSI pin.I try to use SPI1. PA1 configured...

The STM32H725/735 HAL function IS_TIM_MASTER_INSTANCE() is missing a check for TIM12, which is a valid master (has MMS bits in CR2).

For example, here is the function definition for the STM32H725:/****** TIM Instances : master mode available (TIMx_CR2.MMS available )********/#define IS_TIM_MASTER_INSTANCE(INSTANCE) (((INSTANCE) == TIM1) || \                      ((INSTANCE) == TIM...
