Although using the above table will guarantee stability, it is
recommended to use the Print Preview function in
CyClocksRT to determine the correct charge pump settings for
optimal jitter performance.
PLL stability cannot be guaranteed for values below 16 and
above 1023. If values above 1023 are needed, use
CyClocksRT to determine the best charge pump setting.
Clock Output Settings: CLKSRC – Clock Output Cross-
point Switch Matrix [44H(7..0)], [45H(7..0)], [46H(7..6)]
CLKOE – Clock Output Enable Control [09H(5..0)]
Every clock output can be defined to come from one of seven
unique frequency sources. The CLKSRC(2..0) crosspoint
switch matrix defines which source is attached to each
individual clock output. CLKSRC(2..0) is set in Registers 44H,
45H, and 46H. The remainder of register 46H(5:0) must be
written with the values stated in the register table when writing
register values 46H(7:6).
In addition, each clock output has individual CLKOE control,
set by register 09H(5..0).
When DIV1N is divisible by four, then CLKSRC(0,1,0) is
guaranteed
to
be
rising
CLKSRC(0,0,1). When DIV1N is six, then CLKSRC(0,1,1) is
edge
phase-aligned
with
guaranteed
CLKSRC(0,0,1).
When DIV2N is divisible by four, then CLKSRC(1,0,1) is
guaranteed
to
be
rising
CLKSRC(1,0,0). When DIV2N is divisible by eight, then
CLKSRC(1,1,0) is guaranteed to be rising edge phase-aligned
with CLKSRC(1,0,0).
Each clock output has its own output enable, controlled by
register 09H(5..0). To enable an output, set the corresponding
CLKOE bit to 1. CLKOE settings are in
Table 13

The output swing of LCLK1 through LCLK4 is set by V

output swing of CLK5 and CLK6 is set by V
