Notes 1. The frequency that can be used for the peripheral hardware clock (f
A serial clock to be generated can be specified by using baud rate generator control register 0 (BRGC0).
Select the clock to be input to the 5-bit counter by using bits 7 and 6 (TPS01 and TPS00) of BRGC0.
Bits 4 to 0 (MDL04 to MDL00) of BRGC0 can be used to select the division value (f
counter.
The baud rate can be calculated by the following expression.
• Baud rate =
f
k:
XCLK0
: Frequency of base clock selected by the TPS01 and TPS00 bits of the BRGC0 register

Value set by the MDL04 to MDL00 bits of the BRGC0 register (k = 8, 9, 10, ..., 31)
supply voltage and product specifications.
• 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.

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%.
