CAPSTAT is a read-only, special function register (SFR) to indicate a state of the capture circuit.
[Description of Bits]
•
CAPF0 (bit 0)
The CAPF0 bit is the flag to indicate whether data is captured in capture data register 0 (CARP0) or not. When the
CAPF0 bit is set to "1", it indicates that data is captured in capture data register 0 (CAPR0).
When the CAPF0 bit is set to "1", the next capture operation is stopped. So perform the write operation to capture
data register 0 (CAPR0) to clear the CAPF0 bit to "0".
CAPF0 Description
0 No capture 0 latch (initial value)
1 Capture 0 latch
•
CAPF1 (bit 1)
The CAPF1 bit is the flag to indicate whether data is captured in capture data register 0 (CARP1) or not. When the
CAPF0 bit is set to "1", it indicates that data is captured in capture data register 0 (CAPR1).
When the CAPF1 bit is set to "1", the next capture operation is stopped. So perform the write operation to capture
data register 1 (CAPR1) to clear the CAPF0 bit to "0".
CAPF1 Description
0 No capture 1 latch (initial value)
1 Capture 1 latch
