// Register access is all performed through the standard CMSIS structure-based
// interface. This includes module-level structure definitions with members and
// bitfields corresponding to the physical registers and bitfields within each
// module. In addition, Ambiq has provided instance-level macros for modules
// that have more than one physical instance and a generic AM_REGVAL() macro
// for directly accessing memory by address.
//
// The following examples show how to use these structures and macros:
