the Chip Erase ongoing bit in the status bytes received after the STATUS_REQUEST
command.

Disables the AW. The AW will respond with an ACK response and then disable itself.
34.6.7.8 2_PIN_MODE
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.
34.6.7.9 MEMORY_WRITE
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:
1. The number of data
bytes to write + 5 (size and starting address) in the length field.
2. The size of the transfer: words, halfwords, or bytes.
3. The starting address of the transfer.
