Table 3. Host and Peripheral Interfaces
1.
"Default"
state refers to the state of the device after initial boot loading and firmware loading is complete.
2.
"Sleep"
state refers to the state of the device after entering Sleep state which is indicated by Active-Low "SLEEP_IND_FROM_DEV" signal.
3. Please refer to
"RS9116N Open Source Driver Technical Reference Manual"
for software programming information in hosted mode.
4. Please refer to
"RS9116W SAPI Programming Reference Manual"
for software programming information in embedded mode.
5. There are some functionalities, such as SLEEP_IND_FROM_DEV, that are available on multiple pins. However, these pins have other multiplexed functionalities.
Any pin can be used based on the required functionality. Customer must note the default states before using appropriate pin.
6. In the application, wherever RS9116 is connected to external host, during power-off state, the host should ensure that all the pins (analog or digital) connected to the
RS9116 are not driven. Else, the pins must be grounded.
