35.2.11 Slave Address Register Ly (SARLy) (y = 0 to 2)
SVA0 Bit (10-Bit Address LSB)
When the 10-bit address format is selected (SARUy.FS bit is 1), this bit functions as the LSB of a 10-bit address and
forms the lower 8 bits of a 10-bit address in combination with the SVA[6:0] bits.
When the ICSER.SARyE bit is set to 1 (SARLy and SARUy enabled) and the SARUy.FS bit is 1, this bit is valid. While
the SARUy.FS bit or SARyE bit is 0, the setting of this bit is ignored.
SVA[6:0] Bits (7-Bit Address/10-Bit Address Lower Bits)
When the 7-bit address format is selected (SARUy.FS bit is 0), these bits function as a 7-bit address. When the 10-bit
address format is selected (SARUy.FS bit is 1), these bits function as the lower 8 bits of a 10-bit address in combination
with the SVA0 bit.
While the ICSER.SARyE bit is 0, the setting of these bits is ignored.
