Basic PC Operation and I/O Processes Section 4-7
4-7-2 Hold Bit Status
Make the settings shown below to determine whether, when the power supply
is turned on, the Forced Status Hold Bit (SR 25211) and/or IOM Hold Bit
(SR 25212) will retain the status that was in effect when the power was last
turned off, or whether the previous status will be cleared.
The Forced Status Hold Bit (SR 25211) determines whether or not the forced
set/reset status is retained when changing from PROGRAM mode to MONI-
TOR mode.
The IOM Hold Bit (SR 25212) determines whether or not the status of IR bits
and LR bits is retained when PC operation is started and stopped.
4-7-3 Program Memory Write-protection
In CPM2C-S PCs, the program memory can be protected by setting bits 00 to
03 of DM 6602 to 1. Bits 04 to 07 determine whether Programming Console
messages are displayed in English or Japanese.
Note DM 6602 itself can still be changed after the program memory has been write-
protected by setting bits 04 to 07 of DM 6602 to 1.
