TBL—Timebase Lower
The value stored in this field is used as the lower part of the timebase register.
12.6.2 Timebase Reference Registers
There are two special-purpose 32-bit read/write timebase reference registers—TBREFU
and TBREFL—associated with the upper and lower parts of the timebase. When there is a
match between the contents of the timebase and the reference register, a reference interrupt
is enabled in the timebase control and status register.
TBREFU—Timebase Reference Upper
These bits represent the 32-bit reference value for the upper part of the timebase.
