Note 2. Note the following points when selecting the TM50 output as the base clock.
Cautions 1. Make sure that bit 6 (TXE0) and bit 5 (RXE0) of the ASIM0 register = 0 when rewriting the MDL04
Remarks 1. f
This register sets port 1 input/output in 1-bit units.
When using the P10/TxD0/SCK10 pin for serial interface data output, clear PM10 to 0 and set the output latch of P10
to 1.
When using the P11/RxD0/SI10 pin for serial interface data input, set PM11 to 1. The output latch of P11 at this time
may be 0 or 1.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
Address: FF21H

• Mode in which the count clock is cleared and started upon a match of TM50 and CR50 (TMC506 = 0)
• PWM mode (TMC506 = 1)
It is not necessary to enable (TOE50 = 1) TO50 output in any mode.
2. Make sure that bit 7 (POWER0) of the ASIM0 register = 0 when rewriting the TPS01 and TPS00
3. The baud rate value is the output clock of the 5-bit counter divided by 2.

5. TMC506: Bit 6 of 8-bit timer mode control register 50 (TMC50)
Start the operation of 8-bit timer/event counter 50 first and then enable the timer F/F inversion operation
(TMC501 = 1).
Start the operation of 8-bit timer/event counter 50 first and then set the count clock to make the duty = 50%.
