The maximum number of ticks that can set to an LPTimer is 0xFFF0FFFF for non MCWDT-B devices.
It is not recommended to use 0xFFFFFFFF. This is to avoid overflowing both C0 and C1. For MCWDT-B devices, the maximum number of ticks that can be set to an LPTimer is 0xFFFFFFFF since C0 and C1 do not cascade.
For CAT1C devices (XMC), cyhal_lptimer_set_match will only trigger a single interrupt.
