 @deffn {Flash Driver} {stm32f1x}
 This driver supports the STM32F0, STM32F1 and STM32F3 microcontroller series from STMicroelectronics.
 The driver is also compatible with the GD32F1, GD32VF103 (RISC-V core), GD32F3 and GD32E23 microcontroller series from GigaDevice.
-The driver also supports the APM32F0 series from Geehy Semiconductor.
+The driver also supports the APM32F0 and APM32F1 series from Geehy Semiconductor.
