3.2 Communication Module Changes

The communication module changes between the F28004x and F28002x devices only affect the number of peripherals. Module functionality is maintained for both devices. Table 2 shows the module instances differences which should be considered when migrating applications between F28004x and F28002x.

Table 2. Communication Module Instances

Module	F28004x	F28002x
LIN	1 - LINA	2 - LINA, LINB
CAN	2 - CANA, CANB	1 - CANA
SCI	2 - SCIA, SCIB	1 - SCIA
SPI	2 - SPIA, SPIB	2 - SPIA SPIB
I2C	1 - I2CA	2 - I2CA, I2CB
PMBUS	1 - PMBUSA	1 - PMBUSA
FSI	1 - FSIA	1 - FSIA
