Struct lpc845_pac::capt::poll_tcnt::POLL_W

pub struct POLL_W<'a> { /* fields omitted */ }

Field POLL writer - Poll counter in (internal) 12-bit counter wraparounds (loosely 1msec), so related to divided FCLK. This expresses time delay between measurement cycles (ie. after one set of X measurements, time before starting next). This count is used to delay before the next set of measurements. Measuring too often wastes power and does not add value since movement of fingers is relatively slow. For low power mode, this must allow for the clock being used (e.g. a 1MHz osc) so 12 bit count will be potentially much longer. That means, lowering the count to get the reasonable delay period.
