ST10R172L - ELECTRICAL CHARACTERISTICS

The ST10R172L is reset in its default state asynchronously with RSTIN. The internal

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

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

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.

The ST10R172L starts execution here at address 00’0000h.

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

Activation of the IO pins is controlled by software
