Register or bit names in bold underline denotes the READ ONLY bits and registers.
Register bits marked “– “ are not used. Writing any value to these bits does not affect the operation.
Reserved are bits reserved for factory test purpose only. Do not attempt to write these locations to values
other than their default to prevent unexpected operation.
Register Bit notations used in this document are as follows.
- Registerxx: Register05 represents the register with Address 0x05
- BIT(s)NAME[MSB:LSB] ; Rev[3:0] represents 4 bits of Rev3, Rev2, Rev1 and Rev0.
-(RegisterAddress[BIT(s)]) ; (0X00[7]) represents Bit 7 of Register address 0x00, ENFE bit
