Operation:
Transfer A to Condition Code Register
TAP
(A)
CCR[15:8]
Description:
Replaces bits 15 to 8 of the condition code register with the content
of accumulator A. Content of A 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 TAP executes. This prevents interrupt exception processing
during the period after the mask changes but before the following in-
struction executes.
