HD6475328-CP10 HITACHI [Hitachi Semiconductor], HD6475328-CP10 Datasheet - Page 441

• Manufacturer Part Number: HD6475328-CP10
• Description: original Hitachi CMOS microcomputer unit (MCU)
• Manufacturer: HITACHI [Hitachi Semiconductor]

Table E-1 Port State (cont)
H: “High” = High level
L: “Low” = Low level
T: High Impedance
keep: If DDR = 0 and DR = 1 in port 5 and 6, Pull-up MOS holds on-state.
Notes:
*1 8 Bit Timer is reset, so P1
*2 On-chip supporting modules are reset. So these pins become input or output ports controlled
*3 BREQ can be accepted and BACK goes LOW.
*4 BACK outputs LOW.
*5 The pins programmed as address bus output LOW and others programmed as input are at the
*6 If DDR = 0 and DR = 1, the pull-up MOS’s keep ON state.
