The Enhanced Serial Peripheral Interface (ESPI) provides the eCOG1X with both SPI master and
slave capability, and has the option of supporting multiple slaves in master mode. It is independent of
the DUSART SPI function, and has further performance improvements and additional features.
The ESPI peripheral has the following main features.
•
•
•
•
•

•
The LCD controller provides the eCOG1X with hardware support for driving simple static or
multiplexed LCDs.
The LCD controller peripheral has the following main features.

New, enhanced SPI peripheral independent of the DUSART.
Supports both master and slave modes.
Programmable single transfer size from 1 to 16 bits.
Programmable serial clock polarity and phase.
Four chip select signals, outputs in master mode and inputs in slave mode.
Supports multiple data transfers (frames) in master mode.
Programmable timer values for chip select delay times.
For use with simple static and multiplexed LCDs.
32 segment and 4 backplane (common) driver outputs.
Supports 1, 2, 3 or 4 way multiplexing.
Provides continuous control of up to 128 display segments.
Automatic display operation with static data.
Programmable 8-bit input clock prescaler.
The port multiplexer can enable subsets of the segment outputs.
Suitable for 3-phase motor control.
Six PWM timer outputs.
•
•
Two independent timebase period counters.
•
•
Double buffered transition value registers.
Programmable output sense.
Programmable 16-bit input clock prescaler.
Asymmetrical and symmetrical period counter modes.
•
•
Output toggle and return-to-zero modes.
•
•
Supports edge-aligned, centre-aligned and user-defined PWM operating schemes.
Guard time or dead time mode.
16 bits resolution.
Sufficient to control a 3-phase full-bridge drive circuit.
Use one timebase counter for 3-phase full bridge drive.
Use two timebase counters for two sets of 3-phase half bridge drive.
In asymmetrical mode, the period counter runs from zero to max, and resets to zero after
one period.
In symmetrical mode, the period counter runs from zero to max and back to zero over two
periods.
In output toggle mode, the outputs change state at each transition match time.
In return-to-zero mode, the outputs are set at the start of each period and cleared at their
transition match times.
