Technical Reference Manual 002-29852 Rev. *B
7.5.3.4 CXPI_CH_STATUS
Description:
Status
Address:
0x4051800C
Offset:
0xC
Retention:
Not Retained
IsDeepSleep:
No
Comment:
The register fields are not retained. This is to ensure that they come up as '0' after coming out
of DeepSleep system power mode.
This is a non-retained register; setting CTL0.ENABLED to '0' clears all status fields to '0'.
Default:
0x0

Bit-fields
Bits Name SW HW Default or
Enum
Description
0:1 RETRIES_COUNT R W 0 Retries count.
The value reflects the number of retries that HW tries
to transmit a header/response.
HW will reset counter (either case below):
1. after successfully transmit the retry attempt
2. SW clears the CMD.TX_HEADER='0'
3. HW clearing CMD.TX_HEADER=0 due to errors
(TX_BIT_ERROR, TX_HEADER_ARB_LOST,
TX_OVERFLOW_ERROR,
TX_UNDERFLOW_ERROR,
TX_DATA_LENGTH_ERROR, and
TX_FRAME_ERROR)
4 HEADER_RESPONSE R W 0 Frame header/response identifier (only valid when
TX_BUSY or RX_BUSY is '1')
'0' - Frame header being transferred.
'1' - Frame response being transferred.
8 TX_BUSY R W 0 Transmitter busy.
- Set to '1' on the start of the following commands:
TX_HEADER, TX_RESPONSE.
- Set to '0' on successful completion of previous
commands or when an error is detected.
