Notes
(1) Software reset causes the same action as pulling the RESET line low but once latched into the control register
the chip is held in a quiescent mode. Exit from this mode is achieved by latching in the required channel
speed option.
(2) Exit from the test mode requires restarting the required speed options (i.e. codes 0 to 4) or loading an unused
control mode.
(3) The action of testing a channel does not alter the speed at which is set, also changing between test (i.e. test 1
to test 2) has no effect on channel speed settings.
