2.1.4
For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and
system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried
out using a register bank. The register contents are automatically saved in the bank after the CPU
accepts an interrupt that uses a register bank. Restoration from the bank is executed by issuing a
RESBANK instruction in an interrupt processing routine.
This LSI has 15 banks. For details, see the SH-2A, SH2A-FPU Software Manual and section 5.8,
Register Banks.

Table 2.1 lists the values of the registers after a reset.
