CONFIGURATION OPTIONS
The SEC2410/SEC4410 can be configured to support the desired interfaces as outlined in the sections below. The
SEC2410/SEC4410 can be programmed using one of the configured interfaces as outlined in Section 22.0, Bootloader.
Programming the SEC2410/SEC4410 using any of the described interfaces is outlined in the Software Development
Reference Guide 6.
2.1
SPI ROM
The SPI ROM must be 1 Mbit or larger and support either 30 MHz or 60 MHz. The frequency used is set using SPD_-
SEL. For 30 MHz operation, this pin must be pulled to ground through a 100 k
Ω resistor. For 60 MHz operation, this pin
must pulled up through a 100 k
Ω resistor. During RESET_N assertion, the SPD_SEL pin is tri-stated. When RESET_N
is negated, the value on the pin is internally latched, and the pin reverts to SPI_DO functionality.
2.2
Supported System Configurations
This chapter illustrates some possible configurations available for SEC2410/SEC4410.
2.2.1
SD PLUS SC CONFIGURATION
This one SD interface, Smartcard and rest are 3.3 Volt GPIOs.
