CHAPTER 23 INTERRUPT FUNCTIONS

23.8.5 Macro service control registers

(1) Macro service control word

The ÂµPD784938âs macro service function is controlled by the macro service control mode register and macro service

channel pointer. The macro service processing mode is set by means of the macro service mode register, and the

macro service channel address is indicated by the macro service channel pointer.

The macro service mode register and macro service channel pointer are mapped onto the part of the internal RAM

shown in Figure 23-20 for each macro service as the macro service control word.

When macro service processing is performed, the macro service mode register and channel pointer values

corresponding to the interrupt requests for which macro service processing can be specified must be set beforehand.
