System clock control
| SYS | Enables the clock for the AHB, the APB bridge, the Cortex-M0 FCLK and HCLK, SysCon, and the PMU. This bit is read only and always reads as 1. 0 (RESERVED): Reserved 1 (ENABLE): Enable |
| ROM | Enables clock for ROM. 0 (DISABLE): Disable 1 (ENABLE): Enable |
| RAM | Enables clock for RAM. 0 (DISABLE): Disable 1 (ENABLE): Enable |
| FLASHREG | Enables clock for flash/EEPROM register interface. 0 (DISABLED): Disabled 1 (ENABLED): Enabled |
| FLASHARRAY | Enables clock for flash/EEPROM array access. 0 (DISABLED): Disabled 1 (ENABLED): Enabled |
| I2C | Enables clock for I2C. 0 (DISABLE): Disable 1 (ENABLE): Enable |
| GPIO | Enables clock for GPIO. 0 (DISABLE): Disable 1 (ENABLE): Enable |
