 Migration SN8P2501B to SN8P2501D

Item

SN8P2501B

T0 timer

In RTC mode, clear T0IRQ must be after

1/2 RTC clock source (32768Hz), or the

RTC interval time is error.

IHRC 16MHz

IHRC_16M and IHRC_RTC modes don't

support Fosc/1 and Fosc/2.

SN8P2501D

No limitation.

No limitation.

SN8P2501D is compatible to SN8P2501B.

SN8P2501B code can transfer to SN8P2501D directly. Program the original SN8 of SN8P2501B into SN8P2501D

directly with writer selection SN8P2501D chip name to program and doesn’t need re-compile again in IDE.
