| help |
| This divisor defines a ratio between processor clock (HCLK) |
| and master clock (MCK): |
| HCLK = MCK / PROC_CLK_DIV |
| Allowed divider values: 1, 3, 4, 16, and 48. |

| help |
| Use an external 32768 Hz clock source for PLL reference |
| clock. |
| |
| Say y if you want to use an external source for the PLL |
| 32KHz reference clock. |
| |
| Say n to use the +/-2% internal silicon oscillator. |

| help |
| Choose a crystal as the external 32KHz source. |
| |
| Say y if you wish to use a crystal as the external |
| 32KHz clock source. |
| |
| Saying n will select the 32KHZ_IN pin as the external |
| 32KHz clock source. |

| help |
| Choose external 32KHz crystal connection. |
| |
| Say y if the crystal is connected parallel between |
| the XTAL1 and XTAL pins. |
| |
| Say n if the crystal is connected single ended to |
| the XTAL2 pin or a 32KHz square wave is on XTAL2. |
