Operation
(1) Initialization
When the power is switched on, the POW flag is assigned via the power-on detector. ALWAYS TURN the CS to
”
L.
”
Regardless of the logic of the POW flag, initialization must be executed. Therefore, ALWAYS SEND the RESET command
(10101010) from the CPU.
This allows the divider, counter and status register of the S-3510 series to be reset. Namely, the second, minute, hour,
day, date, month, and year (00 sec., 00 min., 00 hr., Sunday (1), January (01), 00 year) are set, and the counter starts to
operate upon the falling edge of the CS.
(2) Write to the Status Register
The S-3510 series is provided with a 4-bit status register. To write the data in the register, send the STATUS WRITE
command (1011D3D2D1D0). This data is retrieved in synchronization with the falling edge of the CS.
Upon initialization, (D3, D2, D1, D0) is set to (1, 0, 1, 0).
In other words,
In the S-3510ANFJX, the S-3510ACFJA, 1 Hz is output from TP
OUT
, and the status is set to the 24-hour display
mode.
In the S-3510AEFJX, the S-3510ADFJA, the S-3510AFFJA, 32768 Hz is output from TP
OUT
, and the status is set to
the 24-hour display mode.
When initialization is not executed, the data of the status register is not specified. ALWAYS execute initialization when
switching on the power.
