I2C Mode Timing (1) The signal applied to the USART1 receive signal (terminal) (URXD1) must meet the timing requirements of t(τ) to ensure that the URXS flip-flop is set. The URXS flip-flop is set with negative pulses that meet the minimum-timing condition of t(τ). The operating conditions to set the flag must be met independently from this timing constraint. The deglitch circuitry is active only on negative transitions on the URXD1 line. 5.26 USART1 over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (1) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT t(τ) USART1 deglitch time VCC = 2.2 V, SYNC = 0, UART mode 200 430 800 ns VCC = 3 V, SYNC = 0, UART mode 150 280 500 |
