6 Clock Architecture
6.1 Clock Input Control Registers
6.1.4 APLL1 Rate Register
The APLL1 rate register provides the rate multiplier value to APLL1. When APLL1 reference clock is at
4.096 MHz, the [x16 (multiplied by)] value must be selected. When APLL1 reference clock is at 2.048 MHz, the
[x32 (multiplied by)] value must be selected. A [x1 (multiplied by)] value is provided in order to bypass APLL1.
Table 37. APLL1 Rate Register
6.1.5 Main Inversion Select Register
The main inversion select register controls programmable inversions at various points within the T8110L main
clocking paths and NETREF paths. Internal points allowed for programmable inversion include the following:
