Turbo PMAC On-line Command Specification 392

 {constant} (optional) is an integer from 1 to 65,535 specifying the number of consecutive

memory addresses to be read; if this is not specified, Turbo PMAC assumes a value of 1;

 the second optional {constant} is an integer from 1 to 16 specifying the number of values to be

reported on a single line; if this is not specified, Turbo PMAC will fit as many as it can on one line.

This command causes Turbo PMAC to report the contents of the specified memory word address or range

of addresses to the host (it is essentially a PEEK command). The command can specify either short (24-

bit) words in Turbo PMAC’s X-memory, short (24-bit) words in Turbo PMAC’s Y-memory, or long (48-

bit) words covering both X and Y memory (X-word more significant). This choice is controlled by the

use of the X, Y, or L address prefix in the command, respectively.

If the letter H is used after the R in the command, Turbo PMAC reports back the register contents in

unsigned hexadecimal form, with six digits for a short word, and 12 digits for a long word. If the letter H

is not used, Turbo PMAC reports the register contents in signed decimal form.

Example:

RHX:$078000 ; Request contents of X-reg $078000 (491520) in hex

8F4017 ; Turbo PMAC responds in unsigned hex
