Pipeline Enable & Timing Select Register
These bits always return the value of 0 when read.
For pipeline A:
For pipeline B:

If bits 1 and 0 of pipeline A’s shadow of this register are set such that pipeline A is
enabled, and timing registers OTHER THAN the CR timing registers have been
selected for timing control, then these 2 bits are used to select the dot clock, and
bits 3 and 2 of MSR for the given pipeline are ignored.
However, if bits 1 and 0 of pipeline A’s shadow of this register are set such that the
given pipeline is enabled, and the CR timing registers have been selected for
timing control, then bits 3 and 2 of MSR are used to select the dot clock, and these
2 bits for the given pipeline are ignored.
These bits are reserved and always return a value of 0 when read.
