In this module, for the convenience of code maintenance,
TIMERx is used to indicate the sequence of the timer peripheral.
Different product series TIMERx represent different meanings:
1. For ES32F36xx series:
TIMER0 ----> AD16C4T0
TIMER1 ----> AD16C4T1
TIMER2 ----> GP32C4T0
TIMER3 ----> GP32C4T1
TIMER4 ----> BS16T0
TIMER5 ----> BS16T1
TIMER6 ----> GP16C4T0
TIMER7 ----> GP16C4T1
2. For ES32F393x/ES32F336x/ES32F392x series:
TIMER0 ----> GP16C4T0
TIMER1 ----> GP16C4T1
TIMER2 ----> GP32C4T0
TIMER3 ----> GP32C4T1
TIMER4 ----> BS16T0
TIMER5 ----> BS16T1
TIMER6 ----> GP16C4T2
TIMER7 ----> GP16C4T3
