FLEXIO_TIMCTLn field descriptions (continued)Field Description• When TRGSRC = 1, the valid values for N will depend on PIN, TIMER, SHIFTER fields in theFLEXIO_PARAM register.• When TRGSRC = 0, the valid values for N will depend on TRIGGER field in FLEXIO_PARAMregister.Refer to the chip configuration section for external trigger selection.The internal trigger selection is configured as follows:{N,00} pin 2N input{N,01} shifter N status flag{N,10} pin 2N+1 input{N,11} timer N trigger output23TRGPOLTrigger Polarity0 Trigger active high1 Trigger active low22TRGSRCTrigger Source0 External trigger selected1 Internal trigger selected21–18ReservedThis field is reserved.This read-only field is reserved and always has the value 0.17–16PINCFGTimer Pin Configuration00 Timer pin output disabled01 Timer pin open drain or bidirectional output enable10 Timer pin bidirectional output data11 Timer pin output15–11ReservedThis field is reserved.This read-only field is reserved and always has the value 0.10–8PINSELTimer Pin SelectSelects which pin is used by the Timer input or output.7PINPOLTimer Pin Polarity0 Pin is active high1 Pin is active low6–2ReservedThis field is reserved.This read-only field is reserved and always has the value 0.TIMOD Timer ModeIn 8-bit counter mode, the lower 8-bits of the counter and compare register are used to configure the baudrate of the timer shift clock and the upper 8-bits are used to configure the shifter bit count.In 8-bit PWM mode, the lower 8-bits of the counter and compare register are used to configure the highperiod of the timer shift clock and the upper 8-bits are used to configure the low period of the timer shiftclock. The shifter bit count is configured using another timer or external signal.In 16-bit counter mode, the full 16-bits of the counter and compare register are used to configure either thebaud rate of the shift clock or the shifter bit count.00 Timer Disabled.Table continues on the next page...Chapter 39 FlexIOKL27 Sub-Family Reference Manual , Rev. 5, 01/2016Freescale Semiconductor, Inc. 763
