Notes: 1. There are instances where bus right release and transition to software standby mode
occur simultaneously due to the timing between BREQ and internal operations. In such
cases, standby mode results, but the standby state may be different.
The initial pin states depend on the mode. See section 18, Pin Function Controller, for
details.
2. I: Input, O: Output, H: High-level output, L: Low-level output, Z: High impedance,
K: Input pin with high impedance, output pin mode maintained.
*1 If the standby control register port high-impedance bits are set to 1, output pins become
high impedance.
*2 A21–A18 will become input ports after power-on reset.
*3 Input in the SH7044/SH7045 F-ZTAT version.
*4 General use I/O ports PAn, PBn, PCn, PDn, and PEn, as well as pins multiplexed with
them, are unstable during the RES setup time (t_RESS) immediately after the RES pin
goes to low level.
