An
LTC group
combines eight LTC cells with its input and output lines. This results in
eight LTC groups, LTCG0 to LTCG7.
A
GTC group
combines eight GTC cells with its input and output lines. This results in
four GTC groups, GTCG0 to GTCG3.
An
I/O group
combines eight GPTA I/O lines connected to bi-directional device pins with
its input and output lines. This results in seven I/O groups, IOG0 to IOG6, supporting
56 I/O lines.
An
Output group
combines eight GPTA output lines connected to device pins as an
output. This results in seven output groups, OG0 to OG6, supporting 56 output lines.
The
Clock group
is a group that combines the eight clock bus output signals CLK[7:0]
generated by the clock distribution unit.
The
FPC/INT group
is a group that combines the six level output signals SOL[5:0] of the
FPCs with two external input lines INT[1:0] of the GPTA module.
The
PDL/INT group
is a group that combines the four PDL output lines of the PDL bus
with four external input lines INT[3:0] of the GPTA module.
