GPS RADIONOVA^® RF Antenna Module
Part No. M10382
Some PIO pins are read at system start and can be used to submit some start-up configuration into the boot
process. In the following tables, all default settings (pin left open) are bolded.
SAFEBOOT Configuration
If it is pulled to low level, the system will start up in safe mode using as few configuration settings as possible
and establishing only the minimum functionality reuqired for establishing communication with the host. No
GPS operation is started. This mode is primarily used for production testing.
The state of SAFEBOOT_N at system start is preserved in bit BOOTMODE0 of the special function register
(SF).

CFG_PIN
The CFG_PIN decides whether external parallel FLASH memory is accessed at all. If the CFG_PIN is left
open (i.e. = 1) at power up the receiver reads the configuration from the configuration pins.
The detection of serial FLASH and SPI and serial EEPROM on DDC interfaces is not affected by CFG_PIN. In
default, only pin configurations will be read.
The state of CFG_PIN at system start is preserved in bit BOOTMODE1 of the special function register (SF).
