6.4.5.4 Get Connected Timer/Counter Clock Source — TCgetClock

Gets a timer/counter channel’s currently connected clock source, if it has been configured.

This is not supported on PC214E or other models that have no clock connection registers.

Another function such as TCsetClock or one of the higher-level timer/counter functions has to

set the clock source after registering the board in order for this function to return the current

setting. If the current clock setting is not known, the function will return ERRSUPPORT.

SUPPORTED IN VERSION 4.40 ONWARDS.

i = TCgetClock (h, chip, chan, pclk)

where h short: board handle as issued by the

registerBoardEx function.

chip short: address offset of the timer/counter chip.

One of the following pre-defined constants may

be used:

X1 = 0

X2 = 4

Y1 = 8

Y2 = 12

Z1 = 16

Z2 = 20

chan short: timer/counter channel number within the

chip (0, 1 or 2).

pclk pointer to short: pointer to a short integer

variable into which the current clock source is

to be stored.

Returns short: OK
