2.1.1.2.8 Register 7, Media Card Status
Register 7 is a 8 bit, read only register that reads the “Insert” and “Write Protect” status
of media cards. These functions of these bits are shown in the table below.
2.1.1.2.9 Register 8, DILC Output Pin Mapping
Register 8 is a 8 bit, read/write register that maps DM365 GPIO and SPI2 pins to the
DILC connector. The default data value is 0b11111111. The mapping of these pins is
shown in the table below.
