1.6.13

Sound generation logic (SGL) module

The SGL module has two modes of operation:

•

Amplitude modulated PWM mode for low cost buzzers using any two eMIOS channels

— Monophonic signal with amplitude control

— 8-bit amplitude resolution

— Ability to mix any two eMIOS channels.

— Requires simple external RC lowpass filter

•

Digital sample mode for higher quality sound using one eMIOS channel and eDMA

— Up to 10-bit audio amplitude resolution

— Polyphonic sound synthesis

— Playback of sample based waveforms

— Text-to-speech possibility

— Requires external lowpass filter

1.6.14

Serial communication interface module (UART)

The PXD10 devices include as many as two UART modules and support UART Master mode, UART

Slave mode and UART mode. The modules are UART state machine compliant to the UART 1.3 and 2.0

and 2.1 Specifications and handle UART frame transmission and reception without CPU intervention.

The serial communication interface module offers the following:

•

UART features:

— Full-duplex operation

— Standard non return-to-zero (NRZ) mark/space format

— Data buffers with 4-byte receive, 4-byte transmit

— Configurable word length (8-bit or 9-bit words)

— Error detection and flagging

– Parity, noise and framing errors

— Interrupt driven operation with four interrupts sources

— Separate transmitter and receiver CPU interrupt sources

— 16-bit programmable baud-rate modulus counter and 16-bit fractional

— Two receiver wake-up methods

•

LIN features:

— Autonomous LIN frame handling

— Message buffer to store identifier and as many as 8 data bytes
