Note: The Status Register read command begins with a logic ‘0’ where all other register commands begin with a logic ‘1’.
Bit [15]:FIFTXRX – When set, indicates the transmit register is ready to receive the next byte for transmission (Transmit Mode) or
that the Rx FIFO has reached the preprogrammed limit (Receive Mode). This bit is multiplexed and dependent
on whether you are in the respective Transmit or Receive mode. (Cleared when FIFO read).
Bit [14]:POR – When set, Power-on Reset occurred. (Cleared after Status Reg read).
Bit [13]:FIFOV/UR – When set, indicates transmit register under run or register overwrite (Transmit Mode) or receive FIFO overflow
(Receive Mode). (Cleared after Status Reg read).
Bit [12]:WKINT – When set, indicates a Wake-up timer overflow. (Cleared after Status Reg read).
Bit [11]:EXINT – When set, indicates a High to Low logic level change on interrupt pin (pin 16). (Cleared after Status Reg read).
Bit [10]:LB – When set, indicates the supply voltage is below the preprogrammed limit. See Battery Detect Threshold and Clock
Output Register.
Bit [9]:FIFEMP – When set, indicates receive FIFO is empty.
Bit [8]:RSSI(Rx) – When set and chip in receive mode, this bit indicates that the incoming RF signal is above the preprogrammed
Digital RSSI limit.
AT(TX ) – When in transmit mode this bit indicates that the antenna tuning circuit has detected a strong enough RF signal.
Bit [7]:GDQD – When set, indicates good data quality.
Bit [6]:CRLCK – When set, indicates Clock Recovery is locked.
Bit [5]:AFATGL – For each AFC cycle run, this bit will toggle between logic ‘1’ and logic ‘0’.
Bit [4]:OFFSGN – Indicates the difference in frequency is higher (logic ‘1’) or lower (logic ‘0’) than the chip frequency.
Bit [3..0]:OFF[3..0] – The offset value to be added to the frequency control word (internal PLL). In order to get accurate values the
AFA has to be disabled during the read by clearing the "AFEN" bit in the AFA Register (bit 0).
To read the status register, initiate a command beginning with a ‘0’ and read the remaining bits on the SDO line. All other
commands begin with a ‘1’ so the TRC101 recognizes a command vs. status. See figure 4 for timing reference.
