The pending internal hold states are cancelled and the current internal access cycle (if
any) is completed.
RSTIN pulled low by internal device during internal reset sequence.
The reset condition may ends here if RSTIN pin is sampled high after t
Internal pullup devices are active on the PORT0 lines. Their input level is high if the
respective pin is left open, or is low if the respective pin is connected to an external pull-
down device by resistive high (pullup) after t
The ST10R272L starts execution here at address 00’0000h.
RSTOUT stays active until execution of the EINIT (End of Initialization) instruction.
Activation of the IO pins is controlled by software.
