Enumeration Type Documentation

DMTimer1msClockSource

enum DMTimer1msClockSource

DMTimer 1ms peripheral module.

DMTIMER1 is specialized for accurate 1mS OS Ticks. The DMTimer1 1ms timer functional clock can be selected from one of five sources:

• The system clock (CLK_M_OSC)
• The PER PLL generated 32.768 KHz clock (CLK_32KHZ)
• The TCLKIN external timer input clock
• The on-chip ~32.768 KHz oscillator (CLK_RC32K)
• The external 32.768 KHz oscillator/clock (CLK_32K_RTC)

Function Documentation

DMTimer1ms_AcknowledgeInterrupt()

void DMTimer1ms_AcknowledgeInterrupt

(

void

)

Acknowledge and clear the interrupt flag.

DMTimer1ms_ClearTimerOverflowCount()

void DMTimer1ms_ClearTimerOverflowCount

(

void

)

Clear the content of the TOC register (=0)

DMTimer1ms_Configure()

bool DMTimer1ms_Configure

(

const DMTimer1msClockSource

clockSource

)

Configure the 1ms timer in auto reload mode (generates an interrupt each millisecond).

Note

Timer has to be started once with DMTimer1ms_Reload after the interrupts are enabled

Parameters

configure DMTimer for given clock source

Returns

true if configure is successfully, otherwise false

DMTimer1ms_GetTimerOverflowCount()

uint32_t DMTimer1ms_GetTimerOverflowCount

(

void

)

Get the content of the TOCR register.

Returns

the timer overflow counter

DMTimer1ms_Reload()

void DMTimer1ms_Reload

(

void

)

Reload the timer value (just required once)
