Rev A1, Page 13/33
The iC-TW14 contains a group of 16-bit registers that R/W/F access indicates iC-TW14 configuration param-
are used for all communication between the host pro- eters that can be stored in the FRAM connected to the
cessor and the TW14, as shown in Tables 7 and 8.
iC-PMX in addition to being readable and writeable.
