NOTES:
1. Peripheral units #1 and #2 cannot be driven simultaneously.
When driving a device continuously, do not use it with the drive duty above
20%.
2. The compulsion switch status is available as status data.
3. Resistance for coils L1 and L2 is not less than 24 ohms.
4. Absolute maximum ratings for diodes D1 and D2 (at Ta=25 °C):
Average rectified current Io = 1A
Maximum forward surge current (60Hz,1-cycle sine wave) I
5. Absolute maximum rating for transistors TR1 and TR2 (at Ta = 25 °C):
Collector current Ic = 2A
