FExplanation of the data
(1) Division data: For D0 through D15 (When S = 1, use D4 through D15.)
BU2615S / BU2615FS
(2) CT: Frequency measurement beginning data
1: Beginning of measurement
0: Internal counter is reset, IFIN is pulldown.
(3) Output port control data: P0, P1, P2, P3, P4, P5, P6
1: Open drain output ON (P5 is LO)
0: Open drain output OFF (P5 is HI)
(4) R0, R1, R2, standard frequency data
(5) S: switch between FMIN and AMIN
0: FMIN 1: AMIN
(6) PS: If this bit is set to ON while AMIN is selected,
swallow counter division is possible.
(7) CH: If this bit set to ON, output port P5 goes to
phase comparison output. 0: P5 1: PD2
(8) GT: Frequency measurement time and unlock
detection ON / OFF
(9) TS: Test data. Input(0).
