28 / 68 page  EM78P311N 8-Bit Microcontroller 24 • Product Specification (V1.0) 10.02.2006 (This specification is subject to change without further notice) In Sleep mode, the internal oscillator is turned off and all system operation is halted. Sleep mode is released by /SLEEP pin (level sensitive or edge sensitive can be set by System Control Register (SCR) Bit 0 (REM)). After a warm-up period, the next instruction will be executed which is after the Sleep mode start instruction. Sleep mode can also be released by setting the /RESET pin to low and executing a reset operation. In level sensitive mode, the /SLEEP pin must be confirmed in low level before entering Sleep mode. In edge sensitive mode, Sleep mode is started even when the /SLEEP pin is in high level. Table 4. Wake-up Methods Wake-up Signal Sleep Mode R5 (SIS) = 1+SLEP Instruction Idle Mode R5 (SIS)= 0 + SLEP Instruction Normal Mode R5 (SIS)=(*) 1. Individual interrupt source in IMR1, IMR2 2.
