Write 0 when writing. 0 is returned after a read.
D[8:0]
TCLKP[24:16]
[24:16] for TClock counter cycle
Use these registers to set the TCLK counter cycle. The TCLK counter begins its countdown at the value written
to these registers.
A write operation is valid once values have been written to both registers (TCLKLREG and TCLKHREG).
Caution
The TCLK unit is stopped when all zeros are written.
