12.4.4 Macro Service Control Register
(1) Macro service control word
The macro service function of the
µPD78214 is controlled using the macro service mode registers and macro
service channel pointers. The macro service mode registers specify the mode of macro service processing,
and the macro service channel pointer specifies the address of a macro service channel to be used.
The macro service mode registers and macro service channel pointers are mapped in the internal RAM as
macro service control words for individual macro services as shown in Fig. 12-16.
To perform macro service, it is necessary to set values in the macro service mode register and channel pointer
corresponding to an interrupt request that can be processed by macro service.
