Previously in the KLXX devices the LPTMR was used for ticker/timeout, since they only have 2 PIT channels which are required for regular timer. The KSDK targets have 4 PIT channels, which allows for two 32-bit timers running at 1 MHz. Since PIT timers are 32-bit, and LPTMR 16-bit, this both simplifies it and makes it more efficient. It does cost the remaining 2 PIT channels, but on the other hand leaves the LPTMR free.
