Spi Eeprom - Spectrum Digital TMS320DM6467 Technical Reference

2.9.3 SPI EEPROM

The EVM incorporates a 32 Kilobyte SPI ROM. The ROM interfaces via CBTs to the
DM6467 SPI interface module. The on board interface can be disabled via the
SPI_ENABLE daughter card pin when the pin is pulled high.
2.10 S/PDIF Analog, and Optical Interfaces
The McASP1's AxR[0] pin on the TMS320DM6467 can be configured to operate as a
S/PDIF transmitter. The TMS320DM6467 EVM supports both analog and optical
interfaces. The analog S/PDIF output pin is routed to a driver and filter circuit before
being output on J5. Another driver is used to interface the optical transmitter P3.
2.10.1 Infrared Sensors
The EVM incorporates a TSOP34840 40Khz. infrared receiver. The receiver is an input
to the CPLD where it is available in non-modulated bit form on pin GPO1 or in
modulated form to UART2 Rx pin in CIR format.
Two control bits in CPLD enable or disable this function. The output pins from the
CPLD can also be disabled via the daughter card connector.
