OPS1-0
These two bits select the output phase delay compensation.
8.9.7 ACTL2
Value after reset : 40H
ACLT1S
0: When Layer 1 operates in activate state, ACTL1S pin is pulled to low level. In contrast, if Layer 1 operates in
deactivate state, ACTL1S pin is driven to high level.
1: The ACTL1 output level is programmed by microprocessor.(ACTL2 : ACLT1S)
LC
If ACLTS1is set to “1”, LC bit is programmable by microprocessor.
0: It shows ACTLS1 pin is driven to high level.
1: It shows ACTLS1 pin is driven to low level.
SPU:
If SPU is set to “1”, W6691 can awaked from power down mode.
