code: 504
# set
<module-index>/<port-index> PX_RW_SEQ [<bank>, <page>, <address>, <byte_count>] <value>
# get
<module-index>/<port-index> PX_RW_SEQ [<bank>, <page>, <address>, <byte_count>] ?
Description#
I2C sequential access to a transceiver’s register. When invoked, the <byte_count>
number of bytes will be read or written in one I2C transaction, in which the <value>
is read or written with only a single register address setup. A subsequent invocation will perform a second I2C transaction in the same manner. <bank>
: the bank address, integer, 0x00 - 0xFF (0-255). <page>
: the transceiver page address, integer, 0x00 - 0xFF (0-255). <address>
: the address within the page, integer, 0x00 - 0xFF (0-255).
Actions#
set, get
Parameters#
value
: hex list, the bytes to be read or written in one I2C transaction. The number of bytes in the<value>
equals<byte_count>
.
