Description

Clock Control Register

Fields

FDIV

Fractional Divider Selection

IDIV

Divider Selection

0 (value1): Divider is bypassed.

1 (value2): 1; MCLK = 32 MHz

2 (value3): 2; MCLK = 16 MHz

3 (value4): 3; MCLK = 10.67 MHz

4 (value5): 4; MCLK = 8 MHz

254 (value6): 254; MCLK = 126 kHz

255 (value7): 255; MCLK = 125.5 kHz

PCLKSEL

PCLK Clock Select

0 (value1): PCLK = MCLK

1 (value2): PCLK = 2 x MCLK

RTCCLKSEL

RTC Clock Select

CNTADJ

Counter Adjustment

0 (value1): 1 clock cycles of the DCO1, 64MHz clock

1 (value2): 2 clock cycles of the DCO1, 64MHz clock

2 (value3): 3 clock cycles of the DCO1, 64MHz clock

3 (value4): 4 clock cycles of the DCO1, 64MHz clock

4 (value5): 5 clock cycles of the DCO1, 64MHz clock

1022 (value6): 1023 clock cycles of the DCO1, 64MHz clock

1023 (value7): 1024 clock cycles of the DCO1, 64MHz clock

VDDC2LOW

VDDC too low

0 (value1): VDDC is not too low and the fractional divider input clock is running at the targeted frequency

1 (value2): VDDC is too low and the fractional divider input clock is not running at the targeted frequency

VDDC2HIGH

VDDC too high

0 (value1): VDDC is not too high

1 (value2): VDDC is too high
