DESCRIPTION
NOTE: Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. For CMOS/TTL Voltage levels, ’LOW’
indicates a voltage in the range 0V to VIL and ’HIGH" indicates a voltage in the range VIH to VCC. For RS-232
input voltage levels, ’LOW’ is any voltage < -3V and ’HIGH’ is any voltage > 3V. For RS-232 output voltage levels,
’LOW’ is any voltage < -5V and ’HIGH’ is any voltage > 5V.
