// The TONE timer is not present here, as it currently cannot be set programmatically. It is set
// by defining TIM_IRQ_PRIO in the variant.h or platformio.ini file, which adjusts the default
// priority for STM32 HardwareTimer objects.
#define SWSERIAL_TIMER_IRQ_PRIO_DEFAULT 1 // Requires tight bit timing to communicate reliably with TMC drivers
#define SERVO_TIMER_IRQ_PRIO_DEFAULT 1 // Requires tight PWM timing to control a BLTouch reliably
#define STEP_TIMER_IRQ_PRIO_DEFAULT 2
// Leave priority 1 for serial interrupt.
