Capture Control Register (CAPCON)
CAPCON is a 16-bit register that specifies the valid edge of a signal that is input to the
CAP0 (P3_4)–CAP3 (P3_7) pins, CAP14 (P10_2), CAP15 (P10_3), and, when TMR16
and TMR17 are in CAP mode, to FTM16 (P10_4) and FTM17A (P3_0) pins. Bits 8 to 15
of CAPCON are used to specify the valid edge of the signal that is input to the CAP14
(P10_2), CAP15 (P10_3), FTM16 (P10_4), and FTM17A (P3_0) pins.
Since CAPCON has only 16-bit access, bit manipulation instructions such as SB and
RB cannot be used.
At reset (when the
RES
signal is input, the BRK instruction is executed, the watchdog
timer is overflown, or an operation code trap is generated), CAPCON becomes 0000H,
and CAP0–CAP3, CAP14, CAP15, FTM16, and FTM17A are specified to the falling
edge.
Figure 11-15 shows the configuration of bits 8–15 of CAPCON.
