44 LOOP1
Notes:
1. When P/S = "L", the register and OR are assigned to SDOS, SMUTE, DFS and LOOP1 pins.
2. When P/S = "L" and DZFE = "L", the groups 1 and 2 are selectable with DZM2-0 bit.
3. This pin changes to OVF pin when OVFE bit is set to "1" in the serial control mode.
4. Do not float any input pins.
