[sdiy] DsPIC timer issue when used as DCO!

[karl dalen]

Since it seams that 32 bit timers cant use the comparator module perhaps
DSI just took the brute force route and OCx output from one 16 bit timer
to the TxCK input of next 16bit timer? The effect would be the same and
compare would be available for toggling. But how did he then implement
the hard sync?
