SSRC3 SSRC2 SSRC1 SSRC0 — ASAM SAMP DONE

bit 7 bit 0

Legend: C = Clearable bit U = Unimplemented bit, read as ‘0’

R = Readable bit W = Writable bit HSC = Hardware Settable/Clearable bit

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7-4 SSRC<3:0>: Sample Clock Source Select bits

1xxx = Unimplemented, do not use

0111 = The SAMP bit is cleared after SAMC<4:0> number of T

AD clocks following the SAMP bit being

set (Auto-Convert mode); no extended sample time is present

0110 = Unimplemented

0101 =TMR1

0100 =CTMU

0011 =TMR5

0010 =TMR3

0001 =INT0

0000 = The SAMP bit must be cleared by software to start conversion

bit 3 Unimplemented: Read as ‘0’

bit 2 ASAM: A/D Sample Auto-Start bit

1 = Sampling begins immediately after last conversion; SAMP bit is auto-set

0 = Sampling begins when SAMP bit is manually set

bit 1 SAMP: A/D Sample Enable bit

1 = A/D Sample-and-Hold amplifiers are sampling

0 = A/D Sample-and-Hold amplifiers are holding

bit 0 DONE: A/D Conversion Status bit

1 = A/D conversion cycle has completed

0 = A/D conversion has not started or is in progress
