7. C Select Register (CSR) (Accessed with RS = 1, Register Number = (B’101)
This register (Figure 33) contains 2 invalid bits (D7 and D6) and 5 valid bits (D5 to D0). It controls C-
type waveforms and is activated only when MDR register’s DWS bits are set for this type of waveform.

CLN
(1) EOR (B-type waveform M signal + no. of counting lines on/off)
1: EOR function on
0: EOR function off
(2) CLN (No. of counting lines in C-type waveform)
1 to 31 should be set in these bits; 0 must not be set.
