Function Documentation

◆ McCpuGetBusClock()

uint32_t McCpuGetBusClock ( void )

Returns: clock frequency value in Hz

The function returns the BUS clock frequency in Hertz.

◆ McCpuGetClock()

uint32_t McCpuGetClock ( void )

Returns: clock frequency value in Hz

The function returns the CPU / MCU clock frequency in Hertz.

◆ McCpuInit()

void McCpuInit ( void )

Perform basic initialisation of the CPU / MCU. This includes:

IRQ vector setup
Stack setup
Clock initialisation
Memory interface setup

◆ McCpuReleaseIrq()

void McCpuReleaseIrq ( void )

The function disables all interrupts and also clears any pending interrupts of the CPU / MCU.

◆ McCpuReset()

void McCpuReset ( void )

The function will issue a reset of the CPU / MCU.
