1 H = HIGH Voltage Level
L = LOW Voltage Level
X = Don’t Care
↑ = LOW to HIGH
↓ = HIGH to LOW
2 PARIN arrives one clock cycle after the data to which it applies.
3 This transition assumes PTYERR is HIGH at the crossing of CLK going HIGH and CLK going LOW. If
PTYERR is LOW, it stays latched LOW for two clock cycles or until RESET is driven LOW.
