Description

MDF clock generator control register

Fields

CKGDEN

CKGEN dividers enable

0 (B_0x0): CKGEN dividers disabled

1 (B_0x1): CKGEN dividers enabled

CCK0EN

MDF_CCK0 clock enable

0 (B_0x0): Bitstream clock not generated

1 (B_0x1): Bitstream clock generated on the MDF_CCK0 pad

CCK1EN

MDF_CCK1 clock enable

0 (B_0x0): Bitstream clock not generated

1 (B_0x1): Bitstream clock generated on the MDF_CCK1 pad

CKGMOD

Clock generator mode

0 (B_0x0): The kernel clock is provided to the dividers as soon as CKGDEN is set to 1.

1 (B_0x1): The kernel clock is provided to the dividers when CKGDEN is set to 1 and the trigger condition met.

CCK0DIR

MDF_CCK0 direction

0 (B_0x0): MDF_CCK0 pin direction is in input.

1 (B_0x1): MDF_CCK0 pin direction is in output.

CCK1DIR

MDF_CCK1 direction

0 (B_0x0): MDF_CCK1 pin direction is in input.

1 (B_0x1): MDF_CCK1 pin direction is in output.

TRGSENS

CKGEN trigger sensitivity selection

0 (B_0x0): A rising edge event triggers the activation of CKGEN dividers.

1 (B_0x1): A falling edge even triggers the activation of CKGEN dividers.

TRGSRC

Digital filter trigger signal selection

2 (B_0x2): mdf_trg[0] selected

3 (B_0x3): mdf_trg[1] selected

15 (B_0xF): mdf_trg[13] selected

CCKDIV

Divider to control the MDF_CCK clock

0 (B_0x0): The MDF_CCK clock is mdf_proc_ck.

1 (B_0x1): The MDF_CCK clock is mdf_proc_ck / 2.

2 (B_0x2): The MDF_CCK clock is mdf_proc_ck / 3.

15 (B_0xF): The MDF_CCK clock is mdf_proc_ck / 16.

PROCDIV

Divider to control the serial interface clock

0 (B_0x0): mdf_ker_ck provided to the SITF

1 (B_0x1): mdf_ker_ck/2 provided to the SITF

CKGACTIVE

Clock generator active flag

0 (B_0x0): The clock generator is not active and can be configured if needed.

1 (B_0x1): The clock generator is active and protected fields cannot be configured.
