NOTE 1: This parameter defines the minimum supply voltage when the data in the program memory RAM remain unchanged. No program
execution should take place during this supply voltage condition.

t(Ï)
USART0: deglitch time
VCC = 3 V, SYNC = 0, UART mode
150 280 500 ns
NOTE 1: The signal applied to the USART0 receive signal/terminal (URXD0) should meet the timing requirements of t(Ï) to ensure that the URXS
flip-flop is set. The URXS flip-flop is set with negative pulses meeting the minimum-timing condition of t(Ï). 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
URXD0 line.
