2.7.2
Four CLAD output pins are provided: CLADO, CLK32, CLK1544, and CLK2048. In Hardware Mode, the CLADO
output provides only a fixed 8 kHz clock. In Host Mode, the CLADO frequency is programmable.
CLAD outputs and frequencies. For pin definitions, see
Table 2-10.
2.7.3
CLAD modes are selected using the CLAD Configuration Register [CLAD_CR; addr 02]; the CLAD Frequency
Select [CSEL; addr 03]; and the CLAD Phase Detector Scale Factor [CPHASE; addr 04]. The CLAD reference
input frequency options are listed in
Table 2-11.
