Legend:
C = Clearable bit
W = Writable bit
‘1’ = Bit is set
HCS = Hardware Clearable/Settable bit
U = Unimplemented bit, read as ‘0’
R = Readable bit
-n = Value at POR
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
ADON: A/D Operating Mode bit(1)
1= A/D Converter module is operating
0= A/D Converter is off
bit 14
bit 13
Unimplemented: Read as ‘0’
ADSIDL: Stop in Idle Mode bit
1= Discontinue module operation when device enters Idle mode
0= Continue module operation in Idle mode
bit 12-10
bit 9-8
Unimplemented: Read as ‘0’
FORM<1:0>: Data Output Format bits
11= Signed fractional (sddd dddd dd00 0000)
10= Fractional (dddd dddd dd00 0000)
01= Signed integer (ssss sssd dddd dddd)
00= Integer (0000 00dd dddd dddd)
bit 7-5
SSRC<2:0>: Conversion Trigger Source Select bits
111= Internal counter ends sampling and starts conversion (auto-convert)
110= CTMU event ends sampling and starts conversion
101= Reserved
100= Timer5 compare ends sampling and starts conversion
011= Reserved
010= Timer3 compare ends sampling and starts conversion
001= Active transition on INT0 pin ends sampling and starts conversion
000= Clearing the SAMP bit ends sampling and starts conversion
bit 4-3
bit 2
Unimplemented: Read as ‘0’
ASAM: A/D Sample Auto-Start bit
1= Sampling begins immediately after the last conversion completes; SAMP bit is auto-set
0= Sampling begins when the SAMP bit is set
bit 1
bit 0
SAMP: A/D Sample Enable bit
1= A/D sample/hold amplifier is sampling input
0= A/D sample/hold amplifier is holding
DONE: A/D Conversion Status bit
1= A/D conversion is done
0= A/D conversion is NOT done
Note 1: Values of ADC1BUFx registers will not retain their values once the ADON bit is cleared. Read out the
conversion values from the buffer before disabling the module.
