6.2.15 IOC81 (TCCC Counter)
The IOC81 (TCCC) is an
If HF (Bit 2 of IOCA0) = 1 and IRE (Bit 3 of IOCA0) = 1, TCCC counter scale uses the low time segments of the pulse generated by Fcarrier frequency modulation (see Fig.
When HP = 0 or IRE = 0, the TCCC is an Up Counter.
NOTE
In TCCC Up Counter mode:
■TCCC
■TCCC
When HP = 1 and IRE = 1, TCCC counter scale uses the low time segments of the pulse generated by Fcarrier frequency modulation.
NOTE
In IR mode:
■Fcarrier = FT/ 2 { [1+decimal TCCC Counter value (IOC81)] * TCCC Scale (IOCA0) }
■FT is system clock: FT = Fosc/1 (CLK=2)
FT = Fosc/2 (CLK=4)
