Pin Functions
Table 2-21
2.4.3 External memory interface of µPD70F3427
The µPD70F3427 is equipped with an external memory interface. The data
bus width can be chosen between 16-bit D[15:0] and 32-bit D[31:0].
The signals of the external memory interface are partly shared with ports
respectively alternative functions and are controlled by different means, as
listed in Table 2-21.
The upper data bus lines D[31:16] are made available by setting
PMC.PMC143 = 1. Thus this bit changes the interface from 16- to 32-bit mode.
All other bus interface signals are available via group 14 (also usable as 3-bit I/
O port) and the permanent MEM-I/F group.
