3.4 Using the LAR, AMR, and IDR for Connections (continued)
3.4.3 Programming Examples
;All programming examples included are in a pseudoassembler format.
;The basic commands used are the “move direct” and “move indirect.”
;A move direct command is indicated by the letters “MD” followed by
;the register name, then the data. Similarly, a move indirect command
;is indicated by the letters “MI” followed by the register name, then by
;data or another register reference (the register may not be indirect).
;The semicolon delineates comments. Direct data is followed by the
;letter “h” for Hex and “b” for binary.
;*******EXAMPLE #1 - Set Up Clocks, Local Bus, H-Bus, and Framers
;
;*******Misc. Stuff
;
MD,AMR,00h
;Define control space
;all specific register names are equivalent
;to the LAR addresses (from Table 11)
;
;
;*******Set up Clocks
;**Main Clock Register
MD,IDR,0C2h
;Load IDR with values for bit slider on, slave mode,
;and synced to ECTF Bus A Clocks
MI,CKM,IDR
;
;The data in IDR is moved into CKM via the LAR register.
;**NETREF Registers
MD,IDR,88h
;Set up NETREF from Local Reference 0, 2.048 MHz bit clock
in, divided value
;value out (i.e., 8 kHz), enable the DJAT connections
;Move the data to CKN
;Set up NETREF divider with divide-by-256
;Move the data to CKND
MI,CKN,IDR
MD,IDR,0FFh
MI,CKND,IDR
;
;**Programmable Clocks
MD,IDR,26h
;This selects the oscillator for the TCLKOUT, A Clock
outputs off, and
;driving ECTF B Clocks
MI,CKP,IDR
;
;Move the data
;**Clock Resources
MD,IDR,40h
;Synced to bus so select Resource divider, x16 on PLL #1 &
x8 PLL #2, SC Clocks off
MI,CKR,IDR
MD,IDR,01h
;Make it so
;Set up Resource divider with divide-by-2 for 4 MHz signal
into PLL #1
MI,CKRD,IDR
;
;Move the data to divider
