Figure 27 External asynchronous hardware reset (power-up reset): Vpp low

1 The ST10R272L is reset in its default state asynchronously with RSTIN. The internal

RAM content may be altered if an internal write access is in progress.

2 On power-up, RSTIN must be asserted t79 after a stabilized CPU clock signal is available.

3 Internal pullup devices are active on the PORT0 lines, so - input level is high if the respec-

tive pin is left open - or is low if the respective pin is connected to an external pulldown

device.

4 The ST10R272L starts execution here at address 00’0000h.

5 RSTOUT stays active until execution of the EINIT (end of initialization) instruction.

6 Activation of the IO pins is controlled by software
