Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-6

Unimplemented:

Read as ‘0’

bit 5

ACONV

: Auto-Conversion Continuous Loop or Single-Shot Mode Select bit

= Continuous Loop mode enabled

= Single-Shot mode enabled

bit 4

ACSCH

: Auto-Conversion Single or Multi-Channel Mode bit

= Multi-Channel mode enabled, Single Channel mode disabled

= Single Channel mode enabled, Multi-Channel mode disabled

bit 3-2

ACMOD<1:0>:

Auto-Conversion Mode Sequence Select bits

If ACSCH = 1:

= Sequential Mode 1 (SEQM1); two samples are taken in sequence:

1st sample: Group A(1)

2nd sample: Group B(1)

= Sequential Mode 2 (SEQM2); four samples are taken in sequence:

1st sample: Group A(1)

2nd sample: Group B(1)

3rd sample: Group C(1)

4th sample: Group D(1)

= Simultaneous Mode 1 (STNM1); two samples are taken simultaneously:

1st sample: Group A and Group B(1)

= Simultaneous Mode 2 (STNM2); two samples are taken simultaneously:

1st sample: Group A and Group B(1)

2nd sample: Group C and Group D(1)

If ACSCH = 0, Auto-Conversion Single Channel Sequence Mode Enabled:

= Single Channel Mode 1 (SCM1); Group A is taken and converted(1)

= Single Channel Mode 2 (SCM2); Group B is taken and converted(1)

= Single Channel Mode 3 (SCM3); Group C is taken and converted(1)

= Single Channel Mode 4 (SCM4); Group D is taken and converted(1)

bit 1

GO/DONE

: A/D Conversion Status bit

= A/D conversion cycle in progress. Setting this bit starts the A/D conversion cycle. If Auto-

Conversion Single-Shot mode is enabled (ACONV = 0), this bit is automatically cleared by

hardware when the A/D conversion (single or multi-channel depending on ACMOD settings) has

completed. If Auto-Conversion Continuous Loop mode is enabled (ACONV = 1), this bit remains

set after the user/trigger has set it (continuous conversions). It may be cleared manually by the user

to stop the conversions.

= A/D conversion or multiple conversions completed/not in progress

bit 0

ADON:

A/D On bit

= A/D Converter module is enabled (after brief power-up delay, starts continuous sampling)

= A/D Converter module is disabled

Note 1:

Groups A, B, C, and D refer to the ADCHS register.
