Is it possible for two PCF8583 chips to use the same watch crystal? My assumption is that they can but would like someone with more technical skills to confirm. The reason I want to use the same crystal is that it will reduce the margin of error between the two timings or atleast they will both be wrong by the same amount.
Basic layout is as follows:
PICAXE (1) PICAXE (2)
: :
PCF8583 (1) PCF8583 (2)
: :
WACTH CRYSTAL
I am using two PCF's as there is a chance that the read command will take place at the same time for both picaxe chips.
Thanks
