Version 1 ColdFire Debug (CF1_DEBUG)
26.4.1.5.21 WRITE_Rn
If the processor is halted, this command writes the 32-bit operand to the selected CPU general-purpose
register (An, Dn). See
If the processor is not halted, this command is rejected as an illegal operation and no operation is
performed.
26.4.1.5.22 WRITE_XCSR_BYTE
Write the special status byte of XCSR (XCSR[31–24]). This command can be executed in any mode.
26.4.1.5.23 WRITE_CSR2_BYTE
Write the most significant byte of CSR2 (CSR2[31
26.4.1.5.24 WRITE_CSR3_BYTE
Write the most significant byte of CSR3 (CSR3[31
26-50
