FLASH_BUSY_WAIT (Bit 7): This enables clock stretching during a flash program or erase operation. |
| 1 = | The BQ40Z50-R4 device will clock stretch (up to the timeout for SMBus devices) during flash operations. |
| 0 = | The BQ40Z50-R4 device will NACK any SMBus engine interrupt that occurs during a flash operation (program or erase). |
| | Note: There is some potential for read errors with this bit. For example, when the master is reading data from the device, there is no NACK from the gauge; therefore, the "NACK" in the hardware releases the bus without writing new data to the SMBDA register, which means the read is whatever is present at the time. PECs should catch this error. |

RSVD(Bit 6): Reserved. Do no
use. |
| | |
BLT1 (Bit 5): Bus low timeout |
1,1 = | 3-s SBS bus low timeout |
1,0 = | 2-s SBS bus low timeout (default) |
0,1 = | 1-s SBS bus low timeout |
0,0 = | No SBS bus low timeout |
| | |
BLT0 (Bit 4): Bus low timeout |
1,1 = | 3-s SBS bus low timeout |
1,0 = | 2-s SBS bus low timeout (default) |
0,1 = | 1-s SBS bus low timeout |
0,0 = | No SBS bus low timeout |
| |
XL (Bit 3): Enables 400-kHz COM mode |
| 1 = | 400-kHz bus speed |
| 0 = | Normal SBS bus speed (default) |
| | |
HPE (Bit 2): PEC on host communication |
| 1 = | Enabled |
| 0 = | Disabled (default) |
| | |
CPE (Bit 1): PEC on charger broadcast |
| 1 = | Enabled |
| 0 = | Disabled (default) |
| | |
BCAST (Bit 0): Enables alert and charging broadcast from device to the host |
1 = | Enabled |
0 = | Disabled (default) |
