(7) Reset function
(8) Output enable function
Only STM mode is pin at the DCM mode BLK: It operates as a switch function of the time of the bran king.
Only STM mode is pin at the DCM mode CMK: It operates as current LIMIT mask function.
When the RST pin is set to High, the excitation position of the output is forcibly set to the initial state, and the MONI
output is placed in the ON state. When RST is then set to Low, the excitation position is advanced by the next STEP
input.
When the OE pin is set High, the output is forced OFF and goes to high impedance.
However, the internal logic circuits are operating, so the excitation position proceeds when the STEP signal is input.
Therefore, when OE is returned to Low, the output level conforms to the excitation position proceeded by the STEP
input.
