TCP1OV

P-5: 20-bit Timer/Counter (TCP1 and TCP2 cascade)

Two sets TCP can be cascaded to form a 20-bit timer/counter when TCP2

chooses TCP1OV as clock source (TCP2S1=1 and TCP2S0=1). In the 20-bit

timer application, user should use TCP1EN to control the starting or stopping

counting of 20-bit timer/counter, data load is controlled by writing TCP1EN=1.

The rising TCP2OV will reload the contents in the pre-load register into

timer/counter, if TCP2LD in TCP2C are enabled. The interrupt feature is

different, in this case, the TCP1 INT will be inhibit when TCP1OV occur, the

TCP2 INT is normally.
