Preprocessor IC for CD and DVD rewritable
7.10.6.2
TIMOUT
For test purposes, any one of the output signals from the EFMTIM block can be routed to
pin TIMOUT. Signals will be output from pin TIMOUT when bit EFMINT = 1 or 0. The value
of register TIM8[2:0] selects which signal is sent to pin TIMOUT as shown in Table 14.
Note, to allow compatibility with the TZA1039, settings 001 and 010 are not used.
7.10.6.3
Bit RST
The EFMTIM block has a local reset input which is software-controlled by bit RST. The
EFMTIM asynchronous reset circuit has to be loaded serially by setting bit RST with the
sequence 0, 1, 0. The reset is actually established after less than 16 edges in signal
EFMc.
After reset, the output signals are left in read state (r/w = RS = TH1 = TH2 = HIGH).
7.10.6.4
Bit EFMTST
Bit EFMTST is used for test purposes only and should be set to logic 0 for normal
operation.
7.11 Normalizer
The Normalizer block produces the servo error signals from the current mode signals Q1
to Q6. It consists of various sub-blocks shown in Figure 15.
