PW0CL and PW0CH are special function registers (SFRs) that function as 16-bit binary counters.
When data is written to either PW0CL or PW0CH, PW0CL and PW0CH is set to “0000H”. The data that is written is
meaningless.
When data is read from PW0CL, the value of PW0CH is latched. When reading PW0CH and PW0CL, use a word type
instruction or pre-read PW0CL.
The contents of PW0CH and PW0CL during PWM operation cannot be read depending on the combination of the
PWM clock and system clock. Table 11-1 shows PW0CH and PW0CL read enable/disable for each combination of the
PWM clock and system clock.

during counting, read consecutively PW0CH or PW0CL twice
until the last data coincides the previous data.
