HALT
RESET
SET_GUARD_TIME
This command tells the CPU to halt code execution for safe programming. If the CPU is not
halted during programming it can start executing partially loaded programs. To halt the proces-
sor, the aWire master should send 0x01 in the data field of the command. After programming the
halting can be released by sending 0x00 in the data field of the command.
Table 31-46. HALT Details
This command resets different domains in the part. The aWire master sends a byte with the
reset value. Each bit in the reset value byte corresponds to a reset domain in the chip. If a bit is
set the reset is activated and if a bit is not set the reset is released. The number of reset domains
and their destinations are identical to the resets described in the JTAG data registers chapter
under reset register.
Table 31-47. RESET Details
Sets the guard time value in the AW, i.e. how long the AW will wait before starting its transfer
after the master has finished.
The guard time can be either 0x00 (128 bit lengths), 0x01 (16 bit lengths), 0x2 (4 bit lengths) or
0x3 (1 bit length).
