Output Controls
S1=1 - OUT1/OUT2 are from
DIV1/DIV2 respectively
S1=0 - Both from DIV2
S3 =1 - OUT3/OUT6 are from
DIV3/DIV6
S3=0 - Both from DIV6
SLEW - see AC Timing
OEM#–output enable mode
x0 - tristated
01 - park low
11 - park high
OEM0 controls OUT0 only
Output Controls
INV1 [CLK1, CLK2]
[0] - normal
[1] - invert clock
OEM1 controls OUT1/OUT2
OEM3 controls OUT3 and OUT6
