2.4.9 Enhanced Modular Input Output System (eMIOS)
The MPC5606BK implements a scaled-down version of the eMIOS module:
• As many as 64 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 2-4 shows the supported eMIOS modes.
Table 2-5 shows the maximum eMIOS channel allocation.
