STR720 - REAL TIME CLOCK (RTC)

155/401

RTCCNT_L

Address Offset: 04h

Reset value: 0000h

Bit 15:0 = RTCCNT[15:0]: RTC CouNTer Low

Reading RTCCNT_L register, the current value of the lower part of RTC Counter register is

returned. To write this register it is required to enter into configuration mode (see RTOFF bit of

RTCCR register).

RTCCNT_M

Address Offset: 08h

Reset value: 0000h

Bit 15:0 = RTCCNT[31:16]: RTC CouNTer Middle

Reading RTCCNT_M register, the current value of the middle part of RTC Counter register is

returned. To write this register it is required to enter into configuration mode (see RTOFF bit of

RTCCR register).

RTCCNT_H

Address Offset: 0Ch

Reset value: 0000h

Bit 15:0 = RTCCNT[47:32]: RTC CouNTer High

Reading RTCCNT_H register, the current value of the high part of RTC Counter register is

returned. To write this register it is required to enter into configuration mode (see RTOFF bit of

RTCCR register).
