Arm Cortex STM32H7: Flash Configuration

Microcontrollers of the STMicroelectronics STM32H7 family have a special Flash Configuration Field where different settings for Flash programming can be adjusted. 

Possible solution

1. Open Hardware | <device> | Configure | FLAGS Configuration.

2. Configure according to your use case:

• Parallelism - The maximum number of bits that can be written to ‘0’ in one shot during a write operation.
• LATENCY - The number of wait states that must be correctly programmed in the Flash access control register (FLASH_ACR) according to the frequency of the bus clock (aclk) and the internal voltage range of the device VCORE.
• WRHIGHFREQ - The optimal programming delay must be accordingly trimmed through this parameter in the FLASH_ACR register.
