Description: Reads byte data from the address specified by general register Rn, and sets the T bit
to 1 if the data is 0, or clears the T bit to 0 if the data is not 0. Then, data bit 7 is set to 1, and the
data is written to the address specified by Rn. During this operation, the bus is not released.
Operation:
Example:
Format
TAS.B @Rn
TAS(long n)
{
}
_LOOP TAS.B @R7
long temp;
temp=(long)Read_Byte(R[n]);
if (temp==0) T=1;
else T=0;
temp|=0x00000080;
Write_Byte(R[n],temp);
PC+=2;

Abstract
When (Rn) is 0, 1
MSB of (Rn)
/* TAS.B @Rn */
_LOOP
T, 1
; R7 = 1000
; Loops until data in address 1000 is 0
