Serial Communications Instructions
Section 3-24
specified, the data in the word or register must always be 0000. An error will
occur and the Error Flag will turn ON if any other constant or a word address
is given and PMCR(260) will not be executed.
R: First Receive Word and Receive Area
Received data is automatically stored in words starting with R+1 and the num-
ber of words received plus R (i.e., including R) is automatically written to R
between 0000 and 00FA hex (0 and 250 decimal).
Setting Before Executing PMCR
Set the data specified by m (beginning with D) as the initial data for the
receive buffer (backup data for receive failure). Data m can be set to 0002 to
00FA (hex) (2 to 255). If 0000 (hex) or 0001 (hex) is specified for m, the initial
value of the receive buffer will be cleared to 0.
Always set a word address for R even if there is no receive data. If a constant
is set, an error will occur, the Error Flag will turn ON, and PMCR(260) will not
be executed. If there is no receive data, R will not be used and can be used for
other purposes.
If there is no operand specified in the execution sequence, such as a direct or
linked word, specify the constant #0000 for R. If a word address or register is
specified, the data in the word or register must always be 0000.
