Comments

Used to determine whether an item defined with view_setting is shown.

Example

ShowDataBlock(bytes, !ShowItem(CME_ReadWriteData));

PLReservedCheck()

PLReservedCheck(reserved_bits)

Comments

Used to make a common check of reserved bits while taking into account the view

settings. If these bits are not zero, a corresponding warning cell will be shown in the

expanded state. Note: only up to 32 bits should be passed to this function.

Example

PLReservedCheck(32);

PLReservedCheck(8);

UnsignedCompare()

UnsignedCompare(op1, op2)

Comments

This function returns difference between integer values and considers them to be

unsigned values. So, the value 0xFFFFFFFF is -1 and less than 0 in logical condi-

tions, but as an unsigned integer it is so much bigger than 0. Use this function in

places where you want integer values to be thought of as unsigned.

Example

select {

(low_limit == high_limit) :

{

...

}

# (AttModifier < low_limit) || (AttModifier >

high_limit) :
