Turbo PMAC/PMAC2 Software Reference
Turbo PMAC On-line Command Specification 354
On-line commands M{constant}, M{constant}->,
.......... M{constant}->{definition}, M{constant}={expression}
Program command M{constant}={expression}
M{constant}->D:{address}
Function: Long Fixed-Point M-Variable Definition
Scope: Global
Syntax: M{constant}[..{constant}]->D[:]{address}
where:
 {constant} is an integer from 0 to 8191 representing the number of the M-variable;
 the optional second {constant} must be at least as great as the first {constant} -- it represents
the number of the end of the range;
 {address} is an integer constant from $000000 to $FFFFFF (0 to 16,777,215 if specified in
decimal).
This command causes Turbo PMAC to define the specified M-variable or range of M-variables to a 48-bit
double word (both X and Y memory; X more significant) at the specified location in Turbo PMAC’s
address space. The data is interpreted as a fixed-point signed (two's complement) integer.
The definition consists of the letter D, an optional colon (:), and the word address.
Memory locations for which this format is useful are labeled with D: in the memory map.
Example:
M161->D:$000088 ; Motor 1 desired position register specified in hex
M161->D134 ; Motor 1 desired position register specified in decimal
M162->D$8B ; Motor 1 actual position register specified in hex

Program command M{constant}={expression}
M{constant}->DP:{address}
Function: Dual-Ported RAM Fixed-Point M-Variable Definition
Scope: Global
Syntax: M{constant}[..{constant}]->DP[:]{address}
where:
 {constant} is an integer from 0 to 8191 representing the number of the M-variable;
 the optional second{constant} must be at least as great as the first {constant} -- it represents
the number of the end of the range;
 {address} is an integer constant from $000000 to $FFFFFF (0 to 16,777,215 if specified in
decimal).
This command causes Turbo PMAC to define the specified M-variable or range of M-variables to point to
32 bits of data in the low 16 bits of both X and Y memory at the specified location in Turbo PMAC’s
address space. The data is interpreted as a fixed-point signed (two’s complement) integer.
The definition consists of the letters DP, an optional colon (:), and the word address.
This format is useful only for dual-ported RAM locations $050000 to $05FFFF (Option 2 is required).
With this format, the host can read or write to the corresponding location with a standard 32-bit integer
data format. The data in the X word is the most significant word, which means on the host side the most
significant word is in the higher of two consecutive addresses (standard Intel format).
