12 / 180 page  TMP93CS32 2004-02-10 93CS32-10 3.3 Standby Function Standby control circuits consist of (1) System clock controller, (2) Prescaler clock controller and (3) Standby controller. Figure 3.3.1 shows a transition figure. Figure 3.3.2 shows the block diagram. Figure 3.3.3 shows I/O registers. Table 3.3.1 shows the internal operation and system clock. Figure 3.3.1 Transition Figure The clock frequency input from X1, X2 pin is called fc. The clock frequency selected by SYSCR1<GEAR2:0> is called system clock fFPH. The devided clock of fFPH is called system clock fSYS, and the 1 cycle of fSYS is called 1 state operating mode. Table 3.3.1 Internal Operation and System Clock Operating Mode Oscillator fc CPU Internal I/O System Clock fSYS RESET Reset Reset fc/32 NORMAL Operate RUN Operate IDLE2 Stop only AD IDLE1 Oscillation Programmable (fc/2, fc/4, fc/8, fc/16, fc/32) STOP Stop Stop Stop Stop Reset NORMAL mode (fc/gear value/2) RUN mode (Stops only CPU) IDLE2 mode (Stops CPU and AD) Interrupt IDLE1 mode (Operates only oscillator) Instruction Interrupt Instruction Interrupt Instruction Release reset Interrupt Instruction STOP mode (Stops all circuits) |
