16.3
The 16-bit capture/compare registers CC16 through CC31 are used as data registers for
capture or compare operations with respect to timers T7 and T8. The capture/compare
registers are not bit-addressable.
Each of the registers CCx may be individually programmed for capture mode or for one
of four different compare modes. Each register may be allocated individually to one of
the two timers T7 or T8, respectively. A special combination of compare modes
additionally allows implementation of a ‘double-register’ compare mode. When capture
or compare operation is disabled for one of the CCx registers, it may be used for general
purpose variable storage.
Capture/Compare Mode Registers for the CAPCOM2 Unit
The functions of the 16 capture/compare registers are controlled by four, identically
organized bit-addressable 16-bit mode control registers named CCM4 … CCM7 (see
description below). Each register contains bits for mode selection and timer allocation of
four capture/compare registers.
