Data_TLB_miss_exception()
{
}
The virtual address (32 bits) at which this exception occurred is set in TEA, and the
corresponding virtual page number (22 bits) is set in PTEH [31:10]. ASID in PTEH indicates
the ASID when this exception occurred.
The PC and SR contents for the instruction at which this exception occurred are saved in SPC
and SSR, and the contents of R15 are saved in SGR.
Exception code H'040 (for a read access) or H'060 (for a write access) is set in EXPEVT. The
BL, MD, and RB bits are set to 1 in SR, and a branch is made to PC = VBR + H'0400.
To speed up TLB miss processing, the offset is separate from that of other exceptions.
TEA = EXCEPTION_ADDRESS;
PTEH.VPN = PAGE_NUMBER;
SPC = PC;
SSR = SR;
SGR = R15;
EXPEVT = read_access ? H'00000040 : H'00000060;
SR.MD = 1;
SR.RB = 1;
SR.BL = 1;
