73M1822/73M1922 Data Sheet
DS_1x22_017
Throughout this document, type W is read/write, type WO is write only and type R is read only. Registers
and bits are defined as 0x16[3:0], where 0x16 is the register address and the numbers in square brackets
specify the address bits. The bit order is [msb – lsb] for a field. For example, [3:0] means bits 3 through 0
of a particular field.
