Table 41. Pattern Start Control Register

Bit

Bit Name

Default

Access

Bit Description

pattern_phase_out

R/W

The bit defines the way how a pattern is being stopped when the

pattern_enable register is cleared. If the bit is set to 0 and the

pattern_enable register is cleared the running pattern stops immediately. If

the bit is set to 1 and the pattern_enable is cleared the pattern finishes the

running frame and stops afterwards.

0: Stop pattern immediately

1: Phase-out pattern

pattern_enable

Starts the pattern generation on current sources.

0: Pattern generation off

1: Start of pattern generation

pattern_start_src

R/W

Selects the input source to trigger the pattern generation start.

0: Pattern enable by software bit

1: pattern enable by GPIO/AUDIO_IN
