Table 35. Output Control Bits For Complementary Output With A Break Event Occurrence - Holtek HT32F50231 User Manual

32-Bit Arm ® Cortex ® -M0+ MCU
HT32F50231/HT32F50241
Channel Complementary Output with Break Function
The Channel complementary outputs, CHxO and CHxNO, are enabled by a combination of the
CHxE, CHxNE, CHMOE, CHOSSR, CHOSSI control bits.

Notes: 1. The MT_CHx pin is the MCTM I/O Pin.
2. The MT_CHx_OEN and MT_CHxN_OEN signals are the MCTM I/O pin output enable combinational
logic control signals which are active low.
