RCAP2L.7 RCAP2L.6 RCAP2L.5 RCAP2L.4 RCAP2L.3 RCAP2L.2 RCAP2L.1 RCAP2L.0
Mnemonic: RCAP2L
Address: CAh
RCAP2L:This register is used to capture the TL2 value when a timer 2 is configured in capture mode.
RCAP2L is also used as the LSB of a 16-bit reload value when timer 2 is configured in auto-
reload mode.
