MCU
/RST _OUT
CODER SWITCH
SIM CARD
The FPGA is mainly for channel control, volume control, sequence control, clock management, IO
expansion control, encryption algorithm and etc.
2.2.3 Memory
The MCU provides two types of external memory interfaces: external memory interface slow (EMIFS)
and external memory interface fast (EMIFF).
