SFR Definition 17.10. RCAP2H: Timer 2 Capture Register High Byte
SFR Definition 17.9. RCAP2L: Timer 2 Capture Register Low Byte
The RCAP2L register captures the low byte of Timer 2 when Timer 2 is configured in capture
mode. When Timer 2 is configured in auto-reload mode, it holds the low byte of the reload
value.
The RCAP2H register captures the high byte of Timer 2 when Timer 2 is configured in cap-
ture mode. When Timer 2 is configured in auto-reload mode, it holds the high byte of the
reload value.
The TL2 register contains the low byte of the 16-bit Timer 2.
The TH2 register contains the high byte of the 16-bit Timer 2.
