INCDEC_PIN
INCDEC_PIN.
Determines how coarse skew adjustments can be made. The adjustments can be
made via hardware using the INC/DEC pins or with software via the CLAT register.
0: INC and DEC inputs ignored; use CLAT register to adjust skew.
1: INC and DEC inputs control output phase increment/decrement.
6
Reserved
5
FSYNC_ALIGN_PIN FSYNC_ALIGN_PIN.
Realignment of FSYNCOUT can be controlled by the FSYNC_ALIGN input pin
instead of the FSYNC_ALIGN_REG register bit.
0: FSYNC_ALIGN pin ignored. FSYNC_ALIGN_REG register bit controls
FSYNCOUT realignment.
1: FSYNC_ALIGN pin controls FSYNCOUT realignment.
4
CK4_ACTV_PIN
CK4_ACTV_PIN.
If the CKSEL[1]/CK4_ACTV pin is functioning as the CK4_ACTV output (see
CKSEL[1]/CK4_ACTV pin description on CK4_ACTV), the CK4_ACTV_REG sta-
tus bit can be reflected to the CK4_ACTV output pin using the CK4_ACTV_PIN
enable function.
0: CK4_ACTV output pin tristated
1: CK4_ACTV status reflected to output pin.
3
CK3_ACTV_PIN
CK3_ACTV_PIN.
If the CKSEL[0]/CK3_ACTV pin is functioning as the CK3_ACTV output (see
CKSEL[0]/CK3_ACTV pin description on CK3_ACTV), the CK3_ACTV_REG sta-
tus bit can be reflected to the CK3_ACTV output pin using the CK3_ACTV_PIN
enable function.
0: CK3_ACTV output pin tristated.
1: CK3_ACTV status reflected to output pin.
2
CK2_ACTV_PIN
CK2_ACTV_PIN.
The CK2_ACTV_REG status bit can be reflected to the CK2_ACTV output pin
using the
CK2_ACTV_PIN enable function.
0: CK2_ACTV output pin tristated.
1: CK2_ACTV status reflected to output pin.
