208 Conversion Instructions
TOD - Convert to Binary
Coded Decimal (BCD)
Instruction Type: output
The TOD instruction is used to convert the integer source value to BCD
and place the result in the destination.
Addressing Modes and File Types can be used as shown in the following
table:
TOD Instruction Destination Operand
The destination can be either a word address or math register.
The maximum values permissible once converted to BCD are:
• 9999 if the destination is a word address (allowing only a 4-digit
BCD value)
• 32768 if the destination is the math register (allowing a 5-digit BCD
value with the lower 4 digits stored in S:13 and the high order digit
in S:14).
If the destination is the math register, it must be directly addressed as S:13.
S:13 is the only status file element that can be used.
