DISABLE
MEMORY_WRITE
2_PIN_MODE
Disables the AW. The AW will respond with an ACK response and then disable itself.
Table 39-38. DISABLE Details
Enables the DATAOUT pin as an output pin. All responses sent from the aWire slave will be sent
on this pin, instead of the RESET_N pin, starting with the ACK for the 2_PIN_MODE command.
Table 39-39. DISABLE Details
This command enables programming of memory/writing to registers on the SAB. The
MEMORY_WRITE command allows words, halfwords, and bytes to be programmed to a contin-
uous sequence of addresses in one operation. Before transferring the data, the user must
supply:
The 4 MSB of the 36 bit SAB address are submitted together with the size field (2 bits). Then fol-
lows the 4 remaining address bytes and finally the data bytes. The size of the transfer is
specified using the values from the following table:
Table 39-40. Size Field Decoding
