Technical Reference Manual 002-29852 Rev. *B
23.9.4 SCB_CMD_RESP_STATUS
Description:
Command/response status
Address:
0x4060000C
Offset:
0xC
Retention:
Not Retained
IsDeepSleep:
No
Comment:
The register fields reflect register states without a default/reset value (CURR_RD_ADDR and
CURR_WR_ADDR) or reflect an external bus state. Therefore, these registers are undefined
after the IP is enabled.
Default:
0x0

Bit-fields
Bits Name SW HW Default or
Enum
Description
0:8 CURR_RD_ADDR R W Undefined I2C/SPI read current address for CMD_RESP mode.
HW increments the field after a read access to the
memory buffer. However, when the last memory buffer
address is reached, the address is NOT incremented
(but remains at the maximum memory buffer address).
The field is used to determine how many bytes have
been read (# bytes = CURR_RD_ADDR -
CMD_RESP_CTRL.BASE_RD_ADDR).
This field is reliable when there is no bus transfer. This
field is potentially unreliable when there is a ongoing
bus transfer, i.e. when CMD_RESP_EC_BUSY is '0',
the field is reliable.
16:24 CURR_WR_ADDR R W Undefined I2C/SPI write current address for CMD_RESP mode.
HW increments the field after a write access to the
memory buffer. However, when the last memory buffer
address is reached, the address is NOT incremented
(but remains at the maximum memory buffer address).
The field is used to determine how many bytes have
been written (# bytes = CURR_WR_ADDR -
CMD_RESP_CTRL.BASE_WR_ADDR).
This field is reliable when there is no bus transfer. This
field is potentially unreliable when there is a ongoing
bus transfer, i.e. when CMD_RESP_EC_BUSY is '0',
the field is reliable.
