57 / 1692 page  2. Programming Model Rev.1.00 Jan. 10, 2008 Page 27 of 1658 REJ09B0261-0100 (DBR), which can only be accessed in privileged mode. Some bits of the status register (such as the RB bit) can only be accessed in privileged mode. (4) System Registers System registers comprise the multiply-and-accumulate registers (MACH/MACL), the procedure register (PR), and the program counter (PC). Access to these registers does not depend on the processing mode. (5) Floating-Point Registers and System Registers Related to FPU There are thirty-two floating-point registers, FR0–FR15 and XF0–XF15. FR0–FR15 and XF0– XF15 can be assigned to either of two banks (FPR0_BANK0–FPR15_BANK0 or FPR0_BANK1– FPR15_BANK1). FR0–FR15 can be used as the eight registers DR0/2/4/6/8/10/12/14 (double-precision floating- point registers, or pair registers) or the four registers FV0/4/8/12 (register vectors), while XF0– XF15 can be used as the eight registers XD0/2/4/6/8/10/12/14 (register pairs) or register matrix XMTRX. System registers related to the FPU comprise the floating-point communication register (FPUL) and the floating-point status/control register (FPSCR). These registers are used for communication between the FPU and the CPU, and the exception handling setting. Register values after a reset are shown in table 2.1. |
