(4) Combined compare registers (MCMPkHW) (k = 1 to 4)
672
Remarks 1. New data must only be written to registers MCMPkHW if the corresponding bit MCMPCk.TEN = 0.
The 16-bit MCMPkHW registers combine the sine and cosine registers MCMPk0 and MCMPk1. Via these
registers it is possible to read or write the contents of MCMPk0 and MCMPk1 in a single instruction.
These registers can be read/written in 16-bit units.
This register is cleared by any reset.
Address: F9C2H, F9C4H, F9C6H, F9C8H
