Conditions for Occurrence
In the selection of an output function (TPU, MMT, or SCI) susceptible to this bug, as shown in
table 17.12, if a switch is made to another output function when a pin output value is low, the pin
may become fixed at low output.
Usage Notes
With the applicable pins listed in table 17.12, do not switch to general port output or an
address/data output function after TPU, MMT, or SCI output function selection.
Also, if a break is to be transmitted by means of a general port output function when performing
serial data transmission from SCI channel 2, execute the break transmission while serial data
transmission is not being performed (the TxD2 pin goes to the idle state (high output) while serial
data data is not being transmitted, so this bug does not occur).
