System Options Register 2
| RTCCLKOUTSEL | RTC clock out select 0 (0): RTC 1 Hz clock is output on the RTC_CLKOUT pin. 1 (1): RTC 32.768kHz clock is output on the RTC_CLKOUT pin. |
| CLKOUTSEL | CLKOUT select 0 (000): FlexBus CLKOUT 2 (010): Flash clock 3 (011): LPO clock (1 kHz) 4 (100): MCGIRCLK 5 (101): RTC 32.768kHz clock 6 (110): OSCERCLK0 |
| FBSL | FlexBus security level 0 (00): All off-chip accesses (instruction and data) via the FlexBus are disallowed. 1 (01): All off-chip accesses (instruction and data) via the FlexBus are disallowed. 2 (10): Off-chip instruction accesses are disallowed. Data accesses are allowed. 3 (11): Off-chip instruction accesses and data accesses are allowed. |
| PTD7PAD | PTD7 pad drive strength 0 (0): Single-pad drive strength for PTD7. 1 (1): Double pad drive strength for PTD7. |
| TRACECLKSEL | Debug trace clock select 0 (0): MCGOUTCLK 1 (1): Core/system clock |
| PLLFLLSEL | PLL/FLL clock select 0 (0): MCGFLLCLK clock 1 (1): MCGPLLCLK clock |
| USBSRC | USB clock source select 0 (0): External bypass clock (USB_CLKIN). 1 (1): MCGPLLCLK/MCGFLLCLK clock divided by the USB fractional divider. See the SIM_CLKDIV2[USBFRAC, USBDIV] descriptions. |
