Port 6; Overview; Table 7.9 Input Pull-Up Transistor States (Port 5) - Hitachi H8/3062 Hardware Manual

P5PCR is initialized to H'F0 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting.
Table 7.9 summarizes the states of the input pull-ups in each mode.

Port 6

7.7.1

Overview

Port 6 is an 8-bit input/output port that is also used for input and output of bus control signals
(LWR, HWR, RD, AS, BACK, BREQ, WAIT) and for clock (φ) output.
The port 6 pin configuration is shown in figure 7.6.
See table 7.11 for the selection of the pin functions.
Pins in port 6 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
