TDP
Operation:
Transfer D to Condition Code Register
TDP
(D)
CCR[15:4]
Description:
Replaces bits 15 to 4 of the condition code register with the content
of accumulator D. Content of D is not changed.
To make certain that conditions for termination of LPSTOP and WAI
are correct, interrupts are not recognized until after the instruction
following TDP executes. This prevents interrupt exception process-
ing during the period after the mask changes but before the follow-
ing instruction executes.
