bit 15 ADRC: A/D Conversion Clock Source bit
1 = A/D internal RC clock
0 = Clock derived from system clock
bit 14-13 Unimplemented: Read as ‘0’
bit 12-8 SAMC4:SAMC0: Auto-Sample Time bits
11111 = 31 TAD
·····
00001 = 1 TAD
00000 = 0 TAD (not recommended)
bit 7-0 ADCS7:ADCS0: A/D Conversion Clock Select bits
11111111 = 128 • TCY
······
00000001 = TCY
00000000 = TCY/2
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
