Notes
.
For a fixed address, the SMBus address of the PES32NT24AG2 slave interface is
0b1110111
by default
and is configurable using DIP Switches SW10[5] and SW10[6] as described in Table 2.15.
The slave SMBus interface responds to the following SMBus transactions initiated by an SMBus master.
Initiation of any SMBus transaction other than those listed above produces undefined results. See the
SMBus 2.0 specification for a detailed description of the following transactions:
–
Byte and Word Write/Read
–
Block Write/Read
SMBus Master Interface
Connected to the master SMBus interface are twenty-two 16-bit I/O Expanders (MAX7311AUG) and a
serial EEPROM, U77 (24LC512). The I/O Expanders are used as the interface for the onboard hot-plug
controllers (MIC2591B). The lower three bits of the bus address for the I/O Expander 0 through 20 are fixed
through the stuffing resistor as 0x20, 0x22, 0x24, 0x26, 0x28, 0x2A, 0x2C, 0x2E, 0x50, 0x52, x54, 0x56,
0x58, 0x5A, 0x5C, 0x5E, 0xB0, 0xA2, 0xA4, 0xA6, 0xA8, and 0xAA, respectively.
Note:
Hot-plug is not implemented when the PES32NT24AG2 is installed.
The seven bits address for the selected EEPROM device is fixed at
0b1010_000
by default.
JTAG Header
The PES32NT24AG2 provides a JTAG connector J73 for access to the PES32NT24AG2 JTAG inter-
face. The connector is a 2.54 x 2.54 mm pitch male 14-pin connector. Refer to Table 2.16 for the JTAG
Connector J73 pin out.
