79 / 158 page ![]() eKTF6708 8-Bit Microcontroller IC Product Specification (V1.2) 03.12.2020 69 (This specification is subject to change without prior notice) Only one event (from Events 3 to 6) can be enabled before entering into Sleep mode. That is: a) If WDT is enabled before SLEP, the eKTF6708 can wake up only when Events 1 or 2 occurs. Refer to Section 6.5 Interrupt for further details. b) If External (/INT) pin change is used to wake up the eKTF6708 and the EXWE bit is enabled before SLEP (with WDT disabled), the eKTF6708 can only wake up when Event 3 occurs. c) If Port Input Status Change is used to wake-up the eKTF6708 and the corresponding wake-up setting is enabled before SLEP (with WDT disabled), the eKTF6708 will wake up only when Event 4 occurs. d) With SPI serves as Slave device and the SPIWK bit of Bank0 R11 register is enabled before SLEP (with WDT disabled), the SPI will wake up the eKTF6708 after it receives data. Hence, the eKTF6708 can wake up only when Event 5 occurs. e) When I 2C is serving as Slave device and I2CWK bit of Bank 0 R11 register is enabled before SLEP (with WDT disabled), the I 2C will wake up the eKTF6708 after it receives data. Hence, the eKTF6708 can only be woken up by Event 6. f) If Low voltage detector is used to wake up the eKTF6708 and the LVDWK bit of Bank 0 R10 register is enabled before SLEP, WDT must be disabled by software. Hence, the eKTF6708 can only be woken up by Event 7. g) If AD conversion completed is used to wake up the eKTF6708 and the ADWK bit of Bank 0 R10 register is enabled before SLEP, WDT must be disabled by software. Hence, the eKTF6708 can only be woken up by Event 8. 6.4.1 Summary of Wake-up and Interrupt Mode Operation Wake-up Signal Condition Signal Sleep Mode Idle Mode Green Mode Normal Mode DISI ENI DISI ENI DISI ENI DISI ENI External INT INTWK = 0, EXIE = 0 /INT pin Disable INTWK = 0, EXIE = 1 Wake-up is invalid.
