Limits of Cascading GTCs and LTCs
As shown on
and
, a maximum of 32 GTCs and a maximum of
64 LTCs can be cascaded. In the TC1784, however cascading of GTCs and LTCs is
limited under certain conditions.
If the LTCs are running with the maximum GPTA
®
v5 unit clock of
f
GPTA
=
f
FPI
= 90 MHz,
a maximum of 16 GTCs and 16 LTCs can be connected together. If the GPTA
®
v5 unit
clock
f
GPTA
is reduced, the number of LTCs that can be cascaded increases accordingly.
Only the integer part of the divider ratio as selected by the GPTA0_FDR fractional divider
register determines the maximum number of cascaded GTCs and LTCs.
