24.10.3 Read Operation to Memory-Mapped Locations and SPR Registers
24.10.3.1 Single Read Operation
For a single read access to memory-mapped locations and SPR registers, the following sequence of
operations need to be performed via the auxiliary port:
Freescale Semiconductor
4. The specified address (stored in RWAD field) is incremented to the next word size and the number
5. The tool transmits the next upload/download information public message (TCODE = 19).
6. The upload/download information public message contains:
7. After the completion of this write operation, the device ready for upload/download public message
8. The specified address (in RWAD field) is incremented to the next word size and the number in the
9. Steps 5 through 8 are repeated until the count value in the CNT field of RWA register equals zero.
1. The tool confirms that the device is ready before transmitting download request public message
2. The download request public message contains:
3. Data read from the specified address is stored in the UDI register.
in the CNT field is decremented. The SC field is not cleared.
a) TCODE(19)
b) Write data (write data -> UDI)
(TCODE = 16) is transmitted to the tool indicating that the device is ready for next access.
CNT field is decremented. The SC field is not cleared.
The SC bit is cleared to indicate end of the block write access.
(TCODE = 18).
a) TCODE(18)
b) Access opcode 0xF which signals that subsequent data needs to be stored in the RWA register.
c) Configure the RWA fields as follows:
– Start/complete (1 to indicate start access) -> SC
– Read/write address (read address) -> RWAD
– Read/write (0 to indicate a read access) -> RW
– Word size (32 bits, 16 bits, 8 bits) -> SZ
– Write data (0xXXXXXXXX-> WD [don’t care])
– Privilege (user data/instruction, supervisor data/instruction) > PRV
– Map select (select memory map, 00 or 01) -> MAP
– Access count (0 to indicate single access) -> CNT
For downloading write data to the device for block write operation, the
download request public message (TCODE = 18) should not be used to
write subsequent data to the UDI register. Data written to the UDI register
(via download request message, TCODE 18) is not used by the device for
any read/write operation.
