Freescale Semiconductor
Read from location defined by the previous READ_MEM. The previous READ_MEM command defines
the address, subsequent READ_SAME commands return contents of same address. The example shows
the sequence for reading a 16-bit word size. Byte alignment details are described in
enabled, an ACK pulse is driven before the data bytes are transmitted.
NOTE
READ_SAME{_WS} is a valid command only when preceded by SYNC,
NOP, READ_MEM{_WS}, or another READ_SAME{_WS} command.
Otherwise, an illegal command response is returned, setting the ILLCMD
bit. NOP can be used for inter-command padding without corrupting the
address pointer.
5.4.4.14
READ_BDCCSR
Read the BDCCSR status register. This command can be executed in any mode.
5.4.4.15
SYNC_PC
This command returns the 24-bit CPU PC value to the host. Unsuccessful SYNC_PC accesses return 0xEE
for each byte. If enabled, an ACK pulse is driven before the data bytes are transmitted. The value of 0xEE
is returned if a timeout occurs, whereby NORESP is set. This can occur if the CPU is executing the WAI
instruction, or the STOP instruction with BDCCIS clear, or if a CPU access is delayed by EWAIT. If the
CPU is executing the STOP instruction and BDCCIS is set, then SYNC_PC returns the PC address of the
instruction following STOP in the code listing.
