Test Functions
Description
Syntax: AT@Fn<CR>
Modifier Usage
n=0 Reserved.
n=1 Reserved.
n=2 Delay 100ms.
n=3 Delay 1s.
n=4 Initiate BERT as Rx End.
n=5 Initiate BERT as Rx End.
n=6 CMX868 Status Register Monitor Function 1. Continuously reads and displays
the contents of the Status register. The update rate is based on the S19 register
setting. The function may be aborted by pushing any key.
n=7 CMX868 Status Register Monitor Function 2. Reads and displays the contents
of the Status register when an interrupt occurs. Error message returned after 30
seconds if IRQN does not go low. User must enable IRQN output and set the
appropriate IRQ Mask bit before executing this test command.
n=8 Reserved.
n=9 Reserved.
@RR
CMX868 Device Reset
Sends the General Reset Command to the CMX868 device.
Syntax: AT@RR<CR>
@Rn?
CMX868 Register Read
Command for displaying the contents of a CMX868 device register
Syntax: AT@Rn?<CR>
where n is a valid CMX868 register address (hexadecimal).
Value returned is either in decimal (default) or hex format depending on the setting
of Bit 4 in the S14 register.
@Rn=x
CMX868 Register Write
Command for writing to a CMX868 device register.
Syntax: AT@Rn=x<CR>
where n is a valid CMX868 register address (hexadecimal) and x is the value to be
written (decimal). 8-bit register values should be between 0-255, whilst 16-bit
register values should be between 0-65535.
