Description

I3C timing register 0

Fields

SCLL_PP

SCL low duration in I3C push-pull phases, in number of kernel clocks cycles: tSCLL_PP = (SCLL_PP + 1) x tI3CCLK SCLL_PP is used to generate tLOW (I3C) timing.

SCLH_I3C

SCL high duration, used for I3C messages (both in push-pull and open-drain phases), in number of kernel clocks cycles: tSCLH_I3C = (SCLH_I3C + 1) x tI3CCLK SCLH_I3C is used to generate both tHIGH (I3C) and tHIGH_MIXED timings.

SCLL_OD

SCL low duration in open-drain phases, used for legacy I2C commands and for I3C open-drain phases (address header phase following a START, not a Repeated START), in number of kernel clocks cycles: tSCLL_OD = (SCLL_OD + 1) x tI3CCLK SCLL_OD is used to generate both tLOW (I2C) and tLOW_OD timings (max. of the two).

SCLH_I2C

SCL high duration, used for legacy I2C commands, in number of kernel clocks cycles: tSCLH_I2C = (SCLH_I2C + 1) x tI3CCLK SCLH_I2C is used to generate tHIGH (I2C) timing.
