Note that pin states at power-on depend on the state of the STBY pin and NMI pin. The case in which pins settle* from an
indeterminate state at power-on, and the case in which pins settle* from the high-impedance state, are described below.
After reset release, power-on reset exception handling is started.
Note: * “Settle” refers to the pin states in a power-on reset in each MCU operating mode.
E.1
When the NMI pin level changes from low to high after powering on, the chip goes to the power-on reset state*
high level is detected at the NMI pin. While the chip detects a low level at the NMI pin, the manual reset state*
established. The pin states are indeterminate during this interval. (Ports may output an internally determined value after
powering on.)

Notes: 1. Applies to the ZTAT version only.
2. Except for the H8S/2357 ZTAT, all resets are power-on resets, regardless of the level on the NMI pin.
