MODEM INTERFACE
AP Booting for MODEM
AP Booting for MODEM means that AP provides the boot area (8Kbyte memory) for MODEM.
MODEM can boot using internal Dual-Port SRAM memory inside MODEM_IF block. In this case, AP should
provide 'MODEM Reset pin' and AP should complete boot operation. Also, AP should download the MODEM
boot code into its Dual-Port SRAM. If the chip select of the MODEM is connected to 'XhiCSn', MODEM can boot
without its external Boot Memory (NAND).
