+ * HC32F460 system clock configuration.
+ *
+ * With the HC32 HAL, the various peripheral clocks (including the CPU clock) are derived
+ * from the main PLL (MPLL-P) output (referred to at F_SYSTEM_CLOCK).
+ *
+ * F_SYSTEM_CLOCK is the target frequency of the main PLL, and the PLL is automatically configured
+ * to achieve this frequency.
+ *
+ * The peripheral clocks are the result of integer division of F_SYSTEM_CLOCK.
+ * Their target frequencies are defined here, and the required division factors are calculated automatically.
+ * Note that the division factor must be a power of 2 between 1 and 64.
+ * If the target frequency is not achievable, a compile-time error will be generated.
+ *
+ * Additionally, there are interdependencies between the peripheral clocks, which are described in
+ * Section 4.4 "Working Clock Specifications" of the HC32F460 Reference Manual.
+ * With Arduino core >= 1.2.0, these interdependencies are checked at compile time.
+ * On earlier versions, you are on your own.
+ *
+ * For all clock frequencies, they can be checked at runtime by enabling the 'ALWAYS_VALIDATE_CLOCKS' define.
+ * In MARLIN_DEV_MODE, they will also be printed to the serial console by 'MarlinHAL::HAL_clock_frequencies_dump'.
+ *
+ * See https://github.com/MarlinFirmware/Marlin/pull/27099 for more information.

+ * serial_ports.h - Define Marlin serial port macros and optionally declare ports
+ *
+ * This header defines one or more of the serial ports...
+ *   - MYSERIAL1/2/3 ..... for host devices
+ *   - MMU_SERIAL ........ for Multi-Material color changers
+ *   - LCD_SERIAL ........ for serial LCDs
+ *   - RS485_SERIAL ...... for CAN bus devices
+ *
+ * Before including this header define the following macros:
+ *   - SERIAL_INDEX_MIN, SERIAL_INDEX_MAX to provide the valid range of serial port indexes.
+ *   - _MSERIAL(X) and MSERIAL(X) to provide the instance name of Serial Port X. (Default: MSerial##X)
+ *   - EP_SERIAL_PORT(X) to provide the instance name of Emergency Parser serial port X (if it is special).
+ *   - USB_SERIAL_PORT(X) to provide the instance name of the USB serial port (if any).
+ *   - ETH_SERIAL_PORT(X) to provide the instance name of the Ethernet serial port (if any).
+ *   - DECLARE_SERIAL(X) to declare standard a serial port with the given index.
