MB95130M Series

(7) LIN-UART Timing

Sampling at the rising edge of sampling clock*1 and prohibited serial clock delay*2

(ESCR register : SCES bit

= 0, ECCR register : SCDE bit = 0)

(VCC

= 5.0 V ± 10%, AVSS = VSS = 0.0 V, TA = − 40 °C to + 85 °C)

*1 : Provide switch function whether sampling of reception data is performed at rising edge or falling edge of the

serial clock.

*2 : Serial clock delay function is used to delay half clock for the output signal of serial clock.

*3 : Refer to “ (2) Source Clock/Machine Clock” for tMCLK.
