Reset and Clock Control (RCC)

Modules

mux

Structs

Clocks

CompVals

Compensation cell calibration values. The N-MOS and P-MOS transistors slew rate compensation factors are stored for the three different compensation cells available in the STM32H7RS family.

Functions

clocks

Get the current clock configuration of the chip.

disable

Disables peripheral T.

disable_with_cs

Disables peripheral T.

enable_and_reset

Enables and resets peripheral T.

enable_and_reset_with_cs

Enables and resets peripheral T.

enable_with_cs

Enables and clears the reset for peripheral T.

frequency

Get the kernel clock frequency of the peripheral T.

get_corrected_comp_vals

Obtain the auto-tuned, slew-rate compensation values for the different compensation cells. The errata corrections are applied. Following the errata, these values should be obtained once during production, around 30°C MCU temperature, for each individual board, and stored in non-volatile memory for future use. The stored values should then be applied at power-up to guarantee stable, high-speed operation of the XSPI busses, and other high-speed I/O. While ST does not discuss the application to the GPIO pins in general in the errata, applying the errata compensation to those as well seems to improve the waveform symmetry (eg: MCO). (ES0596, p. 12, Ch 2.2.15 “I/O compensation could alter duty-cycle of high-frequency output signal”)

reinit

Re-initialize the embassy-stm32 clock configuration with the provided configuration.

set_and_enable_comp_vals

Apply static slew-rate compensation values to all compensation cells, and enable them. These should be the corrected values outlined in the errata. (ES0596, p. 12, Ch 2.2.15 “I/O compensation could alter duty-cycle of high-frequency output signal”)
