24.6.4.2 MSC Controller Connections
The MSC interfaces (MSC0 and MSC1) provide a serial communication link typically
used to connect power switches or other peripheral devices. Each output multiplexers of
GPTA0, GPTA1, and LTCA2 generates 7
×
8 = 56 output lines OUT[111:56] grouped
into seven output groups. These 56 output lines OUT[111:56] are wired to 32 MSC0
inputs and 24 MSC1 inputs.
shows the interconnections among the
MSC0/1 modules and the three GPTA modules. The source for each line of the
ALTINL/ALTINH MSC input buses can be selected via a multiplexer connected either to
GPTA0 output x, GPTA1 output x, or LTCA2 output OUTx (x = 56-111).
