The master sends 8 bits of the block read com-
mand code.
The slave asserts an ACK on the data line unless busy.
The master sends a REPEATED START condition.
The master sends the 7-bit slave ID plus a read
bit (high).
SMBALERT
The MAX16070/MAX16071 support the SMBus alert
protocol. To enable the SMBus alert output, set r35h[1:0]
according to Table 22, which configures a Fault1, Fault2,
or ANY_FAULT output to act as the SMBus alert. This
output is open-drain and uses the wired-OR configura-
tion with other devices on the SMBus. During a fault,
8) The slave asserts an ACK on the data line.
9) The slave sends an 8-bit byte count (16).
10) The master asserts an ACK on the data line.
11) The slave sends 8 bits of data.
12) The master asserts an ACK on the data line.
13) Repeat steps 11 and 12 up to 15 times.
14) The slave sends an 8-bit PEC byte.
15) The master asserts a NACK on the data line.
16) The master generates a STOP condition.
the MAX16070/MAX16071 assert ALERT low, signaling
the master that an interrupt has occurred. The master
responds by sending the ARA (Alert Response Address)
protocol on the SMBus. This protocol is a read byte with
09h as the slave address. Th e slave acknowledges the
ARA (09h) address and sends its own SMBus address to
the master. The slave then deasserts ALERT . The master
can then query the slave and determine the cause of the
fault. By checking r1Ch[6], the master can confirm that
the MAX16070/MAX16071 triggered the SMBus alert.
The master must send the ARA before clearing r1Ch[6].
Clear r1Ch[6] by writing a ‘1’.
JTAG Serial Interface
The MAX16070/MAX16071 feature a JTAG port that
complies with a subset of the IEEE ? 1149.1 specifica-
tion. Either the SMBus or the JTAG interface can be used
to access internal memory; however, only one interface
is allowed to run at a time. The MAX16070/MAX16071
do not support IEEE 1149.1 boundary-scan functionality.
The MAX16070/MAX16071 contain extra JTAG instruc-
tions and registers not included in the JTAG specifica-
tion that provide access to internal memory. The extra
instructions include LOAD ADDRESS, WRITE DATA,
READ DATA, REBOOT, SAVE.
