10.2.10 PWM2 Counter Registers (PW2CH, PW2CL)
Address: 0F0B4H
Access: R/W
Access size: 8 bits
Initial value: 00H
Address: 0F0B5H
Access: R/W
Access size: 8 bits
Initial value: 00H
PW2CL and PW2CH are special function registers (SFRs) that function as 16-bit binary counters.
When data is written to either PW2CL or PW2CH, PW2CL and PW2CH is set to “0000H”. The data that is written is
meaningless.
When data is read from PW2CL, the value of PW2CH is latched. When reading PW2CH and PW2CL, use a word type
instruction or pre-read PW2CL.
The contents of PW2CH and PW2CL during PWM operation cannot be read depending on the combination of the
PWM clock and system clock. Table 10-3 shows PW2CH and PW2CL read enable/disable for each combination of the
PWM clock and system clock.

during counting, read consecutively PW2CH or PW2CL twice
until the last data coincides the previous data.
