Table 8. Basic AT Command Set (Command Defaults in Bold) (Continued)
Extended results—Full CPM enabled including ringback detection. Adds ringback detection to
X4 mode.
Long space disconnect—Modem hangs up after 1.5 seconds or more of continuous space while
on-line.
Disable.
Enable.
Hard Reset—This command is functionally equivalent to pulsing the RESET pin low. (See t
Table 6 on page 8.)
Read from serial EEPROM.
Interrupt Read—This command causes the Si2403 to report the lower 8 bits of the interrupt reg-
ister I/O Control 0 (U70). The CID, OCD, PPD, and RI bits are also cleared, and the INT pin (INT
bit in parallel mode) is deactivated on this read.
Write to serial EEPROM.
Program RAM Write—This command is used to upload firmware supplied by Silicon Labs to the
Si2403. The format for this command is AT:Paaaa,xxxx,yyyy,.... where aaaa is the first address in
hexadecimal, and xxxx,yyyy,.... is data in hexadecimal. Only one :P command is allowed per AT
command line. No other commands can be concatenated in the :P command line. This com-
mand is only for use with special files provided by Silicon Laboratories. Do not attempt to use this
command for any other purpose. Use &T6 to display checksum for patch verification.
User-Access Register Read—This command allows the user to read from the user-access regis-
ters. (See pages 35–53.) The format is “AT:Raa”, where
aa
The “AT:R” command causes all the U- registers to be displayed.
User-Access Register Write—This command allows the user to write to the 16-bit user-access
registers. (See page 35.) The format is “AT:Uaa,xxxx,yyyy,zzzz,...” where
aa
xxxx
yyyy
zzzz
etc.
