Note Bits 2 and 3 are write-only.
Cautions 1. The settings of LVS51 and LVR51 are valid in other than PWM mode.
Remarks 1. In PWM mode, PWM output is made inactive by clearing TCE51 to 0.
Address: FF43H
Symbol
TMC51
2. If LVS51 and LVR51 are read, the value is 0.
3. The values of the TMC516, LVS51, LVR51, TMC511, and TOE51 bits are reflected at the TO51 output
2. Perform <1> to <4> below in the following order, not at the same time.
3. When TCE51 = 1, setting the other bits of TMC51 is prohibited.
4. The actual TO51/TI51/P33/INTP4 pin output is determined depending on PM33 and P33 besides
regardless of the value of TCE51.
<1> Set TMC511, TMC516:
<2> Set TOE51 to enable output:
<3> Set LVS51, LVR51 (refer to Caution 1): Timer F/F setting
<4> Set TCE51
