Description
Related data
This data selects the output from the DO pin.
*1. end-UC is the general-purpose counter measurement complete check function.
(1) When end-UC is set and the counter started (CTE = 0
→ 1), the DO pin automatically goes to
the open state.
(2) When the general-purpose counter measurement completes, the DO pin goes to the low
level, and it becomes possible to check for the count complete state.
(3) The DO pin goes to the open state due to the I/O of serial data (when the CE pin is high).
*2
However, when the I/O-1 and I/O-2 pins are specified to be output ports, IN will go to the open
state.
*3: This is invalid if the I/O-5 pin is specified to be an input port.
Note: The DO pin will be in the open state, regardless of the state of the DO pin control data,
during the data input period (the period when CE is high in IN1 or IN2 mode).
Furthermore, the DO pin will output the content of the internal DO serial data in
synchronization with CL, regardless of the state of the DO pin control data during the data
output period (the period when CE is high in OUT mode).
DO cannot be used (it does not change state) in crystal oscillator stopped mode (R0=0,
R1=R2=R3=1).
