Data Sheet
PT7C43390
2-Wire Real-time Clock Module
2)
Real-time data access 2
*1. During reading, set NO_ACK to 1.
*2. During reading, transmit ACK = 0 to PT7C43390 from the master device.
3)
Status register_1 access and status register_2 access
*1. 0: Status register_1 selected, 1: Status register_2 selected
*2. During reading, set NO_ACK to 1.
4)
INT1 register_1 access and INT1 register_2 access
Since data written to and read from INT1 register_1 varies according to the setting of status register_2, be sure to set status
register_2 before reading/writing INT1 register_1. When an alarm is set using status register_2, these registers function as 3-byte
alarm time data registers, and other than that, they function as 1-byte registers. When the selected frequency steady interrupt
setting is set, the data in these registers is frequency duty setting data.
Caution Alarm data and frequency duty data cannot be operated simultaneously.
