Table 16-13 Status Register Description - Motorola DragonBall MC9328MX1 Reference Manual

Bluetooth Accelerator (BTA)
Name
Reserved Reserved—These bits are reserved and should read 0.
Bits 31–16
MS2LSB 2 LSBs of the Current Bluetooth Clock—Returns the 2 LSB bits of the current Bluetooth clock
Bits 15–14 (NATIVECLK or ESTIMATEDCLK).
REC1 Recoverable 1/3 FEC Check—Indicates that
Bit 13 a 1/3 FEC was performed.
Note: Although all 1/3 FEC errors are
"recoverable," the decoded bit may be
incorrect.
REC2 Recoverable 2/3 FEC Check—Indicates that
Bit 12 a correctable 1-bit error occurred.
NREC Non-Recoverable Error in 2/3
Bit 11 FEC—Indicates that a non-recoverable 2/3
FEC (more than 1-bit error) occurred.
CRC16 Payload CRC Error—Indicates an error in the
Bit 10 payload CRC checksum.
HEC8 Packet Header HEC Error—Indicates an
Bit 9 error in packet HEC checking.
Reserved Reserved—These bits are reserved and should read 0.
Bits 8–7
MS NATIVECLK/ESTIMATEDCLK—Indicates
Bit 6 which of the two clocks maintained by the
Bluetooth core is used as SYSTICK.
STATE Operating State of the BTA—Reflects the
Bits 5–3 current operating state of the BTA.
BUF_ADDR Pointer to Long Word Bit Buffer—Points to the long word bit buffer for data reading. The software
Bits 2–0 can read any long word in the bit buffer up to (but not including) the long word currently used by the
BTA. (It can read up to BUF_ADDR-1) The software must keep track of the last long word accessed.
