PRELIMINARY TECHNICAL DATA
When CFR1<14> = 1, this bit automatically synchronously clears (loads zeros into)
the frequency accumulator for one cycle upon reception of the I/O UPDATE
sequence indicator.
CFR1<13>:
AutoClear Phase Accumulator bit.
When CFR1<13> = 0
(default)
, a new frequency tuning word is applied to the inputs
of the phase accumulator, but not loaded into the accumulator.
When CFR1<13> = 1, this bit automatically synchronously clears (loads zeros into)
the phase accumulator for one cycle upon reception of the I/O UPDATE sequence
indicator.
CFR1<12>:
Sine/Cosine select bit.
When CFR1<12> = 0
(default)
, the angle-to-amplitude conversion logic employs a
COSINE function.
When CFR1<12> = 1, the angle-to-amplitude conversion logic employs a SINE
function.
CFR1<11>:
Clear Frequency Accumulator.
When CFR1<11> = 0
(default)
, the frequency accumulator functions as normal.
When CFR1<11> = 1, the frequency accumulator memory elements are
asynchronously cleared.
CFR1<10>:
Clear Phase Accumulator.
When CFR1<10> = 0
(default)
, the phase accumulator functions as normal.
When CFR1<10> = 1, the phase accumulator memory elements are asynchronously
cleared.
CFR1<9>:
SDIO Input Only.
When CFR1<9> = 0 (
default
), the SDIO pin has bi-directional operation (2-wire
serial programming mode).
