Bits [14:12] — KCAM2-KCAM0
Keyclick Amplitude. These bits set the amplitude of the keyclick sound with eight amplitude levels provided.
KCAM[2:0] = 100 = Medium amplitude (default)
KCAM[2:0] = 111 = Maximum amplitude
KCAM[2:0] = 000 = Minimum amplitude
Bit 11 — RESERVED
This bit is reserved, and should be written to 0. If read, it reads back as 0.
Bits [10:8] — KCFR2-KCFR0
Keyclick Frequency. These bits set the frequency of the keyclick sound (frequencies are approximate).

Bits [7:4] — KCLN3-KCLN0
Keyclick Length. These bits set the approximate duration of the keyclick sound, 16 settings for duration are
provided. The formula for the number of periods heard is:
KCLN[3:0] = 0000 = 2 periods of the keyclick sound (min)
KCLN[3:0] = 0001 = 4 periods of the keyclick sound (default)
KCLN[3:0] = 0010 = 6 periods of the keyclick sound
KCLN[3:0] = 0011 = 8 periods of the keyclick sound
KCLN[3:0] = 1111 = 32 periods of the keyclick sound (max)
Bit 3 — RESERVED
This bit is reserved, and should be written as 0. If read, it is read back as 0.
Bit 2 — MONS
Mono Select. This bit determines the position of the mono multiplexer. This multiplexer allows either the left
channel ADC Input or the mono mix of the stereo line outputs to be played out the differential mono output
(MONO+/-).
Table 46. Mono Select
MONS
Description
0
Mono output comes from left ADC input (default).
1
Mono output comes from mono mix of line outputs.
