6.6.2
Table 6.3 shows the data buses used and valid strobes for the access spaces in the H8S/2218
Group.
In a read, the RD signal is valid without discrimination between the upper and lower halves of the
data bus.
In a write, the HWR signal is valid for the upper half of the data bus, and the LWR signal for the
lower half.
The RD, HWR, and LWR signals are not available in the H8S/2212 Group.
