Description
EECLK
4
O
Serial EEPROM Clock
The I
2
C bus clock signal.
EEDATA
5
I
Serial EEPROM Data
The I
2
C data signal.
CCLKO
77
O
Cycle Clock Output
The 8 kHz reference clock output.
CCLKI
78
I
Cycle Clock Input
The 8 kHz reference clock input.
CMC
2
O
Contender Master Control
This output is set via the nscCMCControl.CMC bit (BAR1+Offset 18h[0]).
The value placed on the bit is directly reflected on this pin.
CMCL
3
O
Contender Master Control Link Enabled
This output is set via the nscCMCControl.CMCL bit (BAR1+Offset 18h[1]).
The value of the bit is reflected on the output when HCControl.linkEnable
(BAR0+Offset 50h[17]) is set. Otherwise it is 0.
TESTO
7
O
Test Out
National internal test pin, user must float.
TESTEN#
76
I
Test Enable
National internal test pin, user must tie high.
