I want to put my MKL03Z32CAF4 processor into a low power state LLWU and have it wake from either:
- Switches connected to the LLWU pins - this seems easy or
- The lptmr reaching a count - not sure if this is supported?
Para 19.1 in the Reference Manual says...
"This device has no LLWU module wakeup source and uses the external pin inputs only
of LLWU_P4 and LLWU_P7 as wakeup source to the LLWU module. The internal
peripheral interrupt flags are connected to the platform directly.
Hence, only the following registers and fieldsare functional for this device:
• LLWU_PE2: [WUPE7] and [WUPE4]
• LLWU_F1: [WUF7] and [WUF4]
Am I stuck using the external pins only?
