Macro Definition Documentation
◆ SYS_ENABLE_BOD_RST
| #define SYS_ENABLE_BOD_RST | ( | ) | (SYS->BODCTL |= SYS_BODCTL_BODRSTEN_Msk) |
Enable Brown-out detector reset function.
- Returns
- None
This macro enable Brown-out detect reset function. The register write-protection function should be disabled before using this macro.
◆ SYS_SET_MFP
| #define SYS_SET_MFP | ( | Port, | |
| Bit, | |||
| Func | |||
| ) | (SYS->Port##_MFP = (SYS->Port##_MFP & ~SYS_MFP_##Port##Bit##_Msk) | SYS_MFP_##Port##Bit##_##Func) |
Set pin function.
- Parameters
-
[in] Port GPIO port number. [in] Bit The single or multiple pins of specified gpio port. [in] Func pin function
- Returns
- None
Function Documentation
◆ SYS_delay_10nop()
| void SYS_delay_10nop | ( | uint32_t | u32NopCnt | ) |
Set delay time.
- Parameters
-
[in] u32NopCnt nop count.
- Returns
- None
◆ SYS_DisableBOD()
| void SYS_DisableBOD | ( | void | ) |
This function disable BOD function.
- Returns
- None
◆ SYS_IsRegLocked()
| uint32_t SYS_IsRegLocked | ( | void | ) |
This function check register write-protection bit setting.
- Return values
-
0 Write-protection function is disabled. 1 Write-protection function is enabled.
◆ SYS_LockReg()
| __STATIC_INLINE void SYS_LockReg | ( | void | ) |
Enable register write-protection function.
- Returns
- None
This function is used to enable register write-protection function. To lock the protected register to forbid write access.
◆ SYS_UnlockReg()
| __STATIC_INLINE void SYS_UnlockReg | ( | void | ) |
Disable register write-protection function.
- Returns
- None
This function disable register write-protection function. To unlock the protected register to allow write access.
