KL25 DMA, DMAMUX, LLWU, ADC, LPTMR, TSI, MCG regs. #4

Closed cdbennett closed 11 years ago

cdbennett commented 11 years ago

Added peripheral structures and register constants for KL25Z4 MCU peripherals: DMA, DMAMUX, LLWU, ADC, LPTMR, TSI, and MCG.

Also, PORTx_PCRn_MUX(x) macro made the PIN_MUX_ALTERNATIVE(x) redundant. Fixed PORTx register #define constants PRC -> PCR typo.

In my opinion it would be better to add register map definitions and such when necessary (writing drivers). Also I'll change to DMA to no use ->ch[x] and instead use DMA0, DMA1, etc to maintain the style used by other definitions.

OK, sorry for jumping ahead, it's just that I have been starting to wrote code-- some test programs for now, not a proper driver yet-- using these peripherals so I thought I should contribute the definitions... I am working on alternate kl25 clock init for other modes too, using preprocessor defines like stm32 to select mode -- I especially am interested in FEE with external 32.768 kHz xtal for quick wake/sleep and LPTMR/RTC in sleep mode for time keeping and timed wakeup. As for DMA I thought DMA1 etc. would be good but i stuck w Freescale style, but no reason not to so that's fine. Thanks. Regards, Colin
