| 16 | - Latching of the levels on mode pins when PRESET# is negated, |
| 17 | - Mode monitoring register, |
| 18 | - Reset control of peripheral devices (on R-Car Gen1), |
| 19 | - Watchdog timer (on R-Car Gen1), |
| 20 | - Register-based reset control and boot address registers for the various |
| 21 | CPU cores (on R-Car Gen2 and Gen3, and on RZ/G). |
