OM11059UL schematics Software set-up 4.1 Functionality The RTC PCF85063BTL is controlled via standard SPI-bus interface. Common SPI protocol applies. Theoretically there is no lower speed limit, however a read or write access to the RTC must be finalized within one second after initiating it, otherwise time counter increments could be lost. -
