Tx A1 and A2 Selection
The A1 and A2 Bytes sent to the Tx Line are always taken from the Insert A1 and A2 Locations. TRFRM
(CR11; 1FB[H], Bit 7) and TFRMEXT (CR14; 1FE[H], Bit 7) determine the Insert Location content. The source
selection is shown below where: & = the logical "AND" function, + = the logical "OR" function, and = represents
a control state.
Tx C1/J0 Selection
Controls J0EN0, J0EN1, TXC1EXT (CR14; 1FE[H], Bit 6), TRC1(CR9; 1F9[H], Bit 6),and OA are used to con-
trol the C1 Selection. J0ENx selects the Insert Location as shown in Table 25. If J0EN1 = "1" the Insert loca-
tions consist of a 64-Byte RAM segment. Microprocessor access to these locations is by means of Locations
180[H] - 1BF[H], and is controlled by J0RWEN. When the Multiple Byte J0 messages are input via the TOH
Port, the storage method is controlled by J0ENx. When J0EN(1,0) = "10" the bytes are stored in rotating fash-
ion with no specific starting point. If J0EN(1,0) = "11" the reception of ASCII characters CR and LF, in
sequence, will synchronize the J0 Counter so that the next J0 Byte will be written at the location that is
accessed at address 180[H].
