Valid Read Sequences

SLVS606C – SEPTEMBER 2005 – REVISED FEBRUARY 2007
The TPS65800 always ACKs its own address.
S
hA1
bqA
Upon receiving hA1, TPS65800 starts at wherever the RAM address register is pointing. The START and the
STOP both act as priority interrupts. If the host has been interrupted and is not sure where it left off it can send a
STOP and reset the TPS65800 state machine to the WAIT state; once in WAIT state, the TPS65800 ignores all
activity on the SCL and SDA lines until it receives a START. A repeated START and START in the I2C
specification are both treated as a START.

START and non-hA0 or non-hA1 Address
A START followed by an address which is not bqA0 or bqA1 is NACKed.

Attempt to Specify Non-Allowed READ Address
If the CMD points to a non-allowed READ address (reserved registers), bq sends a NACK back to the host, and
it does not load the address in the RAM address register. Note that TPS65800 NACKS whether a stop is sent or
not.

Attempt to Specify Non-Allowed WRITE Address
If the host attempts to WRITE to a READ-ONLY or non-accessible address TPS65800 ACKS the CMD
containing the allowed READ address, loads the address into the address register and NACKS after the host
sends the next data byte. After issuing the NACK TPS65800 returns to WAIT state. A subsequent hA1 READ
could read this address.
