6.3.1 Programming
6.3.2 Clearing Flags
section 6.3,
the flag register. Any mask register may be programmed by writing to it, but it won't be affected by clearing a flag register.
Flags are cleared by the various "resets" associated with the SerB. The methods of clearing flags are described in
of this datasheet. In summary, any flag may be cleared by Master Reset, a Load Configuration, or by writing to
–
–
–
Load Configuration - Identical to "Partial Reset" except ports and PLLs are not reset.
Configuration Register Reset (registers without shadows) - These resets may be performed anytime on the fly
and they affect only the designated register. They are performed by loading the individual register with a new
value. (Example of the registers affected include the destination IDs).

Shadow Register Programming - These resets may be performed anytime on the fly and they affect only the
designated shadow register. They are performed by loading the individual register with a new value.

All PLLs will be reset.
Any existing state machines will be initialized to a known state.
Any changes are immediate, except JTAG and I
sRIO maintenance packet. The registers may not be programmed through JTAG, or I
Shadow registers and configuration registers with shadows are not affected.
Memory is not affected
Flag registers may be individually cleared using this method. Mask registers are part of the flag register
and will be affected along with any writing to the flag registers for clearing.
Designated error counters and status registers will be cleared (not set to a programmed value).
PLLs are not affected
Any existing state machines are not affected, except possibly as a result of the register changing.
Any changes are immediate
Programming may be done through sRIO maintenance packets, JTAG or I
Only shadow registers are affected.
Memory is not affected
Flag and Flag Mask registers are not affected.
Error counters and status registers are not affected.
PLLs are not affected
No existing state machines are affected.
There is no immediate effect on any configuration register from programming a shadow register. To load
the results of the programming into the designated configuration registers, a "Load Configuration" reset
must subsequently be performed.
Performed with sRIO maintenance packets.
Flag registers are cleared by writing to them. Writing the Wr32 bit within the register designates whether
the write to a flag register is intended to alter the entire register, including destination IDs, or simply clear
flags. Flags may be cleared by writing a "1" to them. Any flag that is written with a "0" will remain
unchanged.
Some flag registers contain real time values, indicated by "RT" in the flag register section. These values
cannot be cleared except by affecting the source of the flag. A new doorbell or interrupt will not be gener-
ated if the RT flag is active.
Error counters and status registers may be associated with flag registers and will be cleared if written to.
