Field Documentation

◆ inputPreScaler

uint32_t TimerP_Params::inputPreScaler

input pre-scaler divisor ro apply

Note: MUST be power of 2 and between 1 and 256 for GP Timer; MAKE sure this value is not 0; This field is valid only when underlying timer is DM Timer.; This field is not valid when underlying timer is RTI Timer. Set to 1 in this case.

◆ inputClkHz

uint32_t TimerP_Params::inputClkHz

Timer input clock in unit of Hz before pre-scaler, system initialization MUST make any system level muxes, PLLs, power required to input this clock are setup properly

Note: MAKE sure this value is not 0

◆ periodInUsec

uint32_t TimerP_Params::periodInUsec

Timer period in units of usecs, internally TimerP_Params::inputClkHz and TimerP_Params.inputPreScaler is used to compute the value to be put inside the timer HW register

Note: When value is 0, periodInNsec is used instead; When both periodInUsec and periodInNsec are non-zero, periodInNsec is used

◆ periodInNsec

uint32_t TimerP_Params::periodInNsec

Timer period in units of nsecs, internally TimerP_Params::inputClkHz and TimerP_Params.inputPreScaler is used to compute the value to be put inside the timer HW register

Note: When value is 0, periodInUsec is used instead; When both periodInUsec and periodInNsec are non-zero, periodInNsec is used

◆ oneshotMode

uint32_t TimerP_Params::oneshotMode

0: continuous mode of operation, 1: oneshot mode of operation

Note: NOT supported for RTI timer, always set to 0 in this case.

◆ enableOverflowInt

uint32_t TimerP_Params::enableOverflowInt

0: Do not enable timer overflow interrupt, 1: enable timer overflow interrupt

◆ enableDmaTrigger

uint32_t TimerP_Params::enableDmaTrigger

0: Do not enable DMA trigger from timer, 1: enable DMA trigger from timer
