How to solve the problem that two mutually exclusive flags in the business logic code of STM8S003K3 both execute the same function [Copy link]

First of all, this is a program controlled by a faucet. The main control board reports data to the display screen driven by ht1621b through the serial port. The display screen will display different icons according to the serial port only after receiving the data from the serial port. The problematic program is attached below. First, after booting up, there is a touch IC button on the display screen, and the icons on the display screen flash in turn (this process is the faucet exhaust process) until the button is pressed for 10 seconds to exit the exhaust. After exiting the exhaust, the water can be discharged in first and second gears by the STM8S to control the booster pump IO port output (the first gear is the half-pressure output controlled by PWM, and the second gear is the full-pressure output). After the booster pump has no work for xmin (x represents the number of minutes), it enters the automatic flushing state. In this state, the booster pump can work in the first gear to clean the water in the water tank. There are two conditions for exiting: one is water shortage, and the other is that the water pump is idling for 5s. Now it can exit when there is water shortage, but the water pump idling for 5s collects data through AD current, but the conditions for exiting when the water pump is idling for 5s and water shortage are different, and SystemStatus.work_mode (working mode: first and second gear water discharge) and SystemStatus.auto_clean (self-cleaning mode flag) are mutually exclusive. SystemStatus.zyb_mode (boost pump is PWM half-pressure output or full-pressure output) belongs to a subset of SystemStatus.work_mode. I don't know how to execute both conditions, but the functions executed are similar. The problematic codes are written below, but I don't know how to solve them?
