Question $1\mathrm{.}6[4]$

You need a delay of $200ms$ between the time that the extruder nozzle reaches the required temperature and when the first g$-$code must be executed. Asume $F_{\text{O}\text{s}\text{c}}=500kHz.$

$1\mathrm{.}6\mathrm{.}1.$ How many instruction cycles are required to implement this delay? $($dec$)[1]$

$1\mathrm{.}6\mathrm{.}2.$ Assuming that you implement the delay using nested loops $($i$.$e$.$ not a timer$)$ as illustrated in the figure below, determine the minimum number of loops that must be nested to realise this delay if the inner loop does not take more than $5T_{CY}$ to execute and any subsequent outer loops do not take more than $3T_{Cr}$ to execute. $($dec$)[1]$

$1\mathrm{.}6\mathrm{.}3.$ Assume that the inner loop takes exactly $5T_{CY}$ between decrements of the counter register and that the inner loop counter register is loaded every time with $249d$ and that the delay added by subsequent outer loop decrements is exactly $3T_{Cr}.($The loop durations of $5T_{CY}$ and $3T_{CY}$ have been arbitrarily chosen for the question paper and do not necessarily relate to a specific code example$).$ Calculate the binary number that will be contained in the inner loop counter register after $100ms.($bin$)[3]$
