LR0 is the Lower 16-bit Read/Write Load Register. Writes to this register load the least-
significant 16 bits of an Intermediate Register. The intermediate Register is not loaded into
the free-running counter until the rising edge of a 1 Hz clock follows a write operation to
LR1. Read operations return the last value written.
