Table 193 Global control 1; global set 80H[3:0]; note 1
Notes
1. Although the ICLKO I/O is independent of ICKS2 and ICKS3, this selection can only be used if ICKS2 = 1.
2. X = don’t care.

ICLK output and back-end clock is line-locked clock LLC from decoder
ICLK output and back-end clock is XCLK from X port
ICLK output is LLC and back-end clock is LLC2 clock
Back-end clock is the ICLK input
IDQ pin carries the data qualifier
IDQ pin carries a gated back-end clock (IDQ AND CLK)
IDQ generation only for valid data
IDQ qualifies valid data inside the scaling region and all data outside the
scaling region
XCLK default output phase, recommended value
XCLK output inverted
XCLK phase shifted by about 3 ns
XCLK output inverted and shifted by about 3 ns
X port output is disabled by software
X port output is enabled by software
X port output is enabled by pin XTRI at logic 0
X port output is enabled by pin XTRI at logic 1
XRDY output signal is A/B task flag from event handler (A = 1)
XRDY output signal is ready signal from scaler path (XRDY = 1 means
SAA7108E; SAA7109E is ready to receive data)
