Item Description
TN The task number of the task in which the error occurred.
PC The content of the program counter.
EXPEV The content of the exception code register.
SR The content of the status register.
PR The content of the procedure register, which is used in calling a subroutine and stores the return
address to the calling routine.
SP The content of the stack pointer -- the register R15 is used as the stack pointer.
GBR The content of the global base register, which stores base addresses to be used in GBR-indirect
addressing with displacement and in indexed GBR-indirect addressing.
MACH The content of the MAC register high, which saves the accumulated value of a MAC (Multiply
and Accumulate) instruction or the result of a MAC or a MUL instruction. When the result of
a MAC operation is a 64-bit value, this register contains the upper 32-bit value.
MACL The content of the MAC register low, which serves the same purpose as MACH. When the
result of a MAC operation is a 64-bit value, this register contains the lower 32-bit value. When
the result of a MAC operation is a 32-bit value, it contains the entire 32-bit value.
Rxx The content of the general register numbered xx.
FPSCR The content of the floating-point status/control register.
FPUL The content of the floating-point communication register, a register via which data transfer is
done between general and floating-point registers.
FRxx The content of the 32-bit floating-point register numbered xx. When FPSCR.PR (19th bit of
the bits 31 thru 0) = 0, these registers contain values of FPRxx_BANK0. When FPSCR.PR =
1, they contain values of FPRxx_BANK1.
XFxx The content of the 32-bit floating-point extension register numbered xx. When FPSCR.PR
(19th bit of the bits 31 thru 0) = 0, these registers contain values of FPRxx_BANK1. When
FPSCR.PR = 1, they contain values of FPRxx_BANK0.
