13. STANDBY
The standby function is intended to reduce the current drain of the device at backup.
13.1
STANDBY BLOCK CONFIGURATION
Fig. 13-1 shows the configuration of the standby block.
As shown in Fig. 13-1, the standby block is further divided into halt control and clock stop control blocks.
The halt control block consists of the halt control circuit, interrupt control block, timer carry FF, and the P0D0/
ADC2 to P0D3/ADC5 pins. It controls the operation of the CPU (program counter, instruction decoder, and ALU
block).
The clock stop control block controls the 8 MHz crystal oscillator, CPU, system register, and control register.
