Note Bits 2 and 3 are write-only.
Cautions 1. The settings of LVS5n and LVR5n are valid in other than PWM mode.
Remarks 1. In PWM mode, PWM output is made inactive by clearing TCE5n to 0.
Address: FF43H
Symbol
TMC51
2. Perform <1> to <4> below in the following order, not at the same time.
3. Stop operation before rewriting TMC5n6.
2. If LVS5n and LVR5n are read, the value is 0.
3. The values of the TMC5n6, LVS5n, LVR5n, TMC5n1, and TOE5n bits are reflected at the TO5n pin
4. n = 0, 1
<1> Set TMC5n1, TMC5n6:
<2> Set TOE5n to enable output: Timer output enable
<3> Set LVS5n, LVR5n (see Caution 1):
<4> Set TCE5n
regardless of the value of TCE5n.
