RCC AHB2 peripheral clocks enable in Sleep and Stop modes register
| GPIOASMEN | IO port A bus clock enable during Sleep and Stop modes Set and cleared by software. Access can be secured by GPIOA SECx. When secure, a non-secure read/write access is RAZ/WI. It does not generate an illegal access interrupt. This bit can be protected against unprivileged access when secure with RCC SPRIV or when non-secure with RCC NSPRIV. 0 (B_0x0): IO port A bus clock disabled by the clock gating during Sleep and Stop modes 1 (B_0x1): IO port A bus clock enabled by the clock gating during Sleep and Stop modes |
