Note Bits 2 and 3 are write-only.
Cautions 1. The settings of LVS50 and LVR50 are valid in other than PWM mode.
Remarks 1. In PWM mode, PWM output is made inactive by clearing TCE50 to 0.
Figure 7-8. Format of 8-Bit Timer Mode Control Register 50 (TMC50) (78K0/KB2-L, 78K0/KC2-L Only)
Address: FF6BH
Symbol
TMC50
2. If LVS50 and LVR50 are read, the value is 0.
3. The values of the TMC506, LVS50, LVR50, TMC501, and TOE50 bits are reflected at the TO50
2. Perform <1> to <4> below in the following order, not at the same time.
3. When TCE50 = 1, setting the other bits of TMC50 is prohibited.
4. The actual TO50/TI50/P17 pin output is determined depending on PM17 and P17 besides
output regardless of the value of TCE50.
<1> Set TMC501, TMC506:
<2> Set TOE50 to enable output:
<3> Set LVS50, LVR50 (refer to Caution 1): Timer F/F setting
<4> Set TCE50
