PIO Read Register 1: RR4
PIO read register RR4 is used for displaying the signal status of general purpose input / output signals XPIO7~0 in X axis and
general purpose input / output signals YPIO7~0 in Y axis. The bit is 0 if the signal is on the Low level; the bit is 1 if the signal is
on the Hi level.

D7 ～ 0 XPIO7 ～ 0
Displaying the status of X axis general purpose input / output signals XPIO7~0.
When XPIO7~0 signals are set as input, it indicates the input state and when set as output, it indicates the
output state.
D15 ～ 8 YPIO7 ～ 0
Displaying the status of Y axis general purpose input / output signals YPIO7~0.
When YPIO7~0 signals are set as input, it indicates the input state and when set as output, it indicates the
output state.

PIO Read Register 2: RR5
PIO read register RR5 is used for displaying the signal status of general purpose input / output signals ZPIO7~0 in Z axis and
general purpose input / output signals UPIO7~0 in U axis. The bit is 0 if the signal is on the Low level; the bit is 1 if the signal is
on the Hi level.

Displaying the status of U axis general purpose input / output signals UPIO7~0.
When UPIO7~0 signals are set as input, it indicates the input state and when set as output, it indicates the
output state.
6.17 Data-Read Register: RR6 / RR7
According to the data-read command, the data of internal registers will be set into registers RR6 and RR7. The low word 16 bits
(RD15 ~ RD0) is set in RR6 register, and the high word 16 bits (RD31 ~ RD16) is set in RR7 register for data reading.
