PrintScriptProgramHz

Purpose: Print the number of times the Command Script processor either checked or executed a Script command during the the prior second.
Assumes:   Nothing.
Passed: Nothing.
Returns: R23:R22   WORD   wLastHz   the wLastScriptHz value that was printed
Alters: R18, R20, R21, the FLAGs (SREG) and the COM1 Transmit buffer
Example: 
.ORG   0x1000

   CALL    APrintScriptProgramHz    ; Also prints Carriage Return and Line Feed
   RET
Test it: 
m>@ 0x1000    ; When no Script was executed during the last second
Script logic Hz: 1
m>@ 0x1000
Script logic Hz: 1
m>S = 0
Next operation pointer: 0x0000
m>m>m>m>m>@ 0x1000
Script logic Hz: 5
m>@ 0x1000
Script logic Hz: 1
m>S
Next operation pointer: 0x00DD
m>                ; No need to be logged in for this alternative
>E 4 ^= 32           ; Toggle BIT_RTC_SEC_SCRIPT_HZ in EEbFlags_RTC

Notes: Note the reported cycles is "1" in the example above, even though no Command Script needed to be executed in the prior second. Upon entry to the Script logic, it checks whether there is any Script to execute. If there is none at that moment, the Script processing logic itself turns the BIT_SM_SCRIPT System Mode BIT off in order not to waste time checking for a Script for the remainer of that second. This means when there is no Script to be run, the Script processor actually does run precisely once each second.
The BIT_SM_SCRIPT BIT is contained in EEbSystemMode BYTE.
The unit Serial Number must be valid for ANY Script to be processed. If it is not, all System Modes (i.e., all those enabled with the EEbSystemMode BYTE) are disabled, but the Command Processor is still enabled.

; Passed:  Nothing.
; Returns: R23:R22  WORD wLastHz the wLastScriptHz value that was printed

The BIT_RTC_SEC_SCRIPT_HZ in EEbFlags_RTC causes this function to be called automatically once each second.
