3.5.7

Boot Assist Module (BAM)

The device implements a Boot Assist Module (BAM):

•

Block of read-only memory containing VLE code which is executed according to boot mode of the

device

•

Download of code into internal SRAM possible via FlexCAN or LINFlex, after which code can be

executed

3.5.8

Enhanced Modular Input Output System (eMIOS)

The MPC5602D implements a scaled-down version of the eMIOS module:

•

Up to 28 timed I/O channels with 16-bit counter resolution

•

Buffered updates

•

Support for shifted PWM outputs to minimize occurrence of concurrent edges

•

Supports configurable trigger outputs for ADC conversion for synchronization to channel output

waveforms

•

Edge-aligned output pulse width modulation

— Programmable pulse period and duty cycle

— Supports 0% and 100% duty cycle

— Shared or independent time bases

•

DMA transfer support available

Table 7 shows the supported eMIOS modes.
