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.
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.
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.
CK1_ACTV_PIN.
The CK1_ACTV_REG status bit can be reflected to the CK1_ACTV output pin
using the CK1_ACTV_PIN enable function.
0: CK1_ACTV output pin tristated.
1: CK1_ACTV status reflected to output pin.
CKSEL_PIN.
If manual clock selection is being used, clock selection can be controlled via the
CKSEL_REG[1:0] register bits or the CKSEL[1:0] input pins.
0: CKSEL pins ignored. CKSEL_REG[1:0] register bits control clock selection.
1: CKSEL[1:0] input pins controls clock selection.
