3.0 Registers
3.7 Status Register Overview
0x3B—CELL_STATUS (Interrupt Status Register)
The CELL_STATUS register is located at address 0x3B.
0x3C—RXFEAC_VER (Receive FEAC/Part Number/Version Number Register)
The RXFEAC_VER register is located at address 0x3C. The lower 8 bits have fixed values. Programming of the
FEAC channel and use of these interrupts is discussed in
