17.3.2.7 Read/Write Load Register 1

LR1 is the Upper 16-bit Read/Write Load Register. Writes to this register load the most-
significant 16 bits of an Intermediate Register. The Intermediate Register is not loaded into
the free-running counter until the rising edge of CLK1HZ. LR0 should be written to first,
followed by LR1, when the counter is to be reinitialized. Reads return the last written value.
