Register Information
The Register Block is organized as follows:
Status Register (SR) (1 Byte). Located at address 00h.
Remote Shut Down Register (RSR) (1 Byte). Located at
address FFh.
Status Register (Volatile)
The Status Register provides the user a mechanism for
checking the status of GATE_H, GATE_M and GATE_L.
These bits are volatile and are read only.
The gate status values in the Status Register can be read at
any time by performing a random read operation. Only one
byte is returned by each read operation. The master should
supply a stop condition following the output byte to be
consistent with the bus protocol.
STAT_GATEH:
GATEH Status Flag (volatile)
STAT_GATEH will be set to ‘1’ when the GATE_H charge
pump is turned on. It will be reset to ‘0’ when the GATE_H
charge pump is turned off.
STAT_GATEM:
GATEM Status Flag (volatile)
STAT_GATEM will be set to ‘1’ when GATE_M charge pump
is turned on. It will be reset to ‘0’ when the GATE_M charge
pump is turned off.
STAT_GATEL:
GATEL Status Flag (volatile)
STAT_GATEL will be set to ‘1’ when GATE_L charge pump
is turned on. It will be reset to ‘0’ when the GATE_L charge
pump is turned off.
The status register also contains a WEL bit that controls
write operations to the Shutdown Register. Bits 7, 6, 5, and 4
should always be set to ‘0’.
WEL:
Write Enable Latch (Volatile)
The WEL bit controls the access to the Remote Shutdown
Register (RSR). This bit is a volatile latch that powers up in
the LOW (disabled) state. While the WEL bit is LOW, writes
to the RSR will be ignored (no acknowledge will be issued
after the Data Byte). The WEL bit is set by writing a “1” to the
WEL bit and zeroes to the other bits of the status register.
The X80200 provides the user with a software shutdown of
GATE_H, GATE_L and GATE_M. This over-rides the normal
output control.
A write operation with data 01h to the RSR will immediately
turn off GATE_M followed by GATE_L. The GATE_L turn off
is delayed by t
DELAY_DOWN
.
A write operation with data 02 to the RSR will turn off
GATE_H.
A write operation with data 03 to RSR will shutdown all
gates. GATE_H turn off at the same time as GATE_M.
GATE_L turns off after a delay of t
DELAY_DOWN
.
A write operation with data 00h to the RSR will remove the
software override function. Assuming all supplies are good,
the X80200 will return to the previous state by first turning on
GATE_H and GATE_L. Then, GATE_M is turned on
according to the power sequencing mode chosen.
Bits 7, 6, 5, 4, 3 and 2 of the Remote Shutdown Register
should always be set to ‘0’.
The data in the RSR can be read by performing a random
read operation to the RSR. The data in the RSR powers up
in ‘0’ state.
Bus Interface Information
Interface Conventions
The device supports a bidirectional bus oriented protocol.
The protocol defines any device that sends data onto the
bus as a transmitter, and the receiving device as the
receiver. The device controlling the transfer is called the
master and the device being controlled is called the slave.
The master always initiates data transfers, and provides the
clock for both transmit and receive operations. Therefore,
the devices in this family operate as slaves in all
applications.
