PWM instruction channel x (PWMICx)
This PWMICx is the dataport that allows the instructions to be loaded into the PWM
channel. The loading of the instructions is achieved by continuously writing to this dataport.
As this dataport address falls on the non-auto increment region, continuous write operation
on I
independent PWM channels. To access these dataports, the corresponding ENx in the
PWMCS register must be set to 0 first to put the PWM channel in reset state.

PWM Instruction Channel x, where x is 7 to 0
As an instruction is 16-bit width, writing the instruction into this 8-bit
PWMICx dataport requires two 8-bit data write. The most significant byte
of the 16-bit instruction is to be written in first and followed by the least
significant byte of the instruction. The same effect applies to the read
operation.
