NOTES:
1.Peripheral units #1 and #2 cannot be driven simultaneously.
When driving a device continuously, do not use drive duty above 20%.
2.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
5.Absolute maximum rating for transistors TR1 and TR2 (at Ta = 25˚C): Collector current Ic = 2A
