The following table describes all the parameters for Fan-in Control of a Linear Binary Counter.

Table 10-35. Fan-in Control Parameters
Parameter	Value
CLR_FANIN	AUTO MANUAL
CLR_VAL	<val> [default value for AUTO is 8, 1 for MANUAL]
LD_FANIN	AUTO MANUAL
LD_VAL	<val> [default value for AUTO is 6, 1 for MANUAL]
CLK_FANIN	AUTO MANUAL
CLK_VAL	<val> [default value for AUTO is 8, 1 for MANUAL]

The following table describes all the functional description of a Linear Binary Counter.

Table 10-36. Functional Description
Data	Aclr	Enable	Sload	Clock	Up down	Qn+1	Tcnt n+1
X	0	X	X	X	X	0’s	0
X	1	X	X	¦	X	Qn	Qn+1== 2width-1
X	1	0	0	¦	X	Qn	Qn+1== 2width-1
m	1	X	1	¦	X	m	Qn+1== 2width-1
X	1	1	0	¦	1	Qn + 1	Qn+1== 2width-1
X	1	1	0	¦	0	Qn - 1	Qn+1== 2width-1

Note: Assume that Aclr is active low, Enable is active high, Sload is active high, Clock is rising and Tcnt is active high.
