Description
15:0 FREQ_DIV
R/W 0000
16-bit Frequency Divider for signal sampling and pattern generation
using samples.
If EN_CARRIER_FREQ = 0 Sampling Freq. = 108MHz/FREQ_DIV
0x0000 - Disabled.
0x0001 - Sampling frequency is 108 MHz,
0x0002 - Sampling/Carrier frequency is 54 MHz
.....
0xFFFF - Sampling/Carrier frequency is 1.648 kHz
If EN_CARRIER_FREQ = 1 Carrier Freq. = 54 MHz/FREQ_DIV
0x0000 - Disabled.
0x0001 - Carrier frequency is 54 MHz
0x0002 - Carrier frequency is 26 MHz
.....
0xFFFF - Carrier frequency is 824 Hz
a _{IO_SEL cannot be written to unless all signal generation and monitoring is disabled (FIFO_MODE = 00 and}
EVENT_MODE = 00).
