/* Write Timer Data Register:
Changing the value of the TDR change the value of the internal
reset latch. However when the timer is stopped the reset value is
reload into TDR in the next MFP cycle (so it seems to be the case
according to my test on a real ST). The tricky point is that as MFP
and CPU clock are separate (for Atari-ST) reading the value just
after a write can occur before the next MFP cycle in which case the
current TDR (not the one written) is returned! Fortunatly we don't
really need to emulate this since it is more a glitch than anything
and no one should have used it!
Motorola Datasheet: the TDRs contain the value of their respective
main counter. This value was captured on the last low-to-high
transistion of the data strobe pin. The main counter is initialized
by writting the to the TDR. If the timer is stopped the data is
loaded simultaneously into both TDR and maincounter. If the TDR is
written to while the timer is enabled, the value is not loaded into
the timer until the timer counts through 01. If a write is
performed while the timer is counting through 01 then an
INDETERMINATE value is loaded into the main counter.
