55 / 124 page  ST7LUS5, ST7LU05, ST7LU09 Power saving modes 55/124 AWUFH prescaler register (AWUPR) In AWU mode, the period that the MCU stays in Halt mode (tAWU in Figure 24 on page 52) is defined by: This prescaler register can be programmed to modify the time that the MCU stays in Halt mode before waking up automatically. Note: If 00h is written to AWUPR, depending on the product, an interrupt is generated immediately after a HALT instruction, or the AWUPR remains unchanged. AWUPR Reset value: 1111 1111 (FFh) 765 432 10 AWUPR[7:0] R/W Table 23. AWUPR register description Bit Name Function 7:0 AWUPR[7:0] Auto Wake-up Prescaler These 8 bits define the AWUPR division factor (as explained below). This prescaler register can be programmed to modify the time that the MCU stays in Halt mode before waking up automatically. Note: If 00h is written to AWUPR, depending on the product, an interrupt is generated immediately after a HALT instruction, or the AWUPR remains unchanged. Table 24.
