99 Some of pins can be driven using the P-MOS and N-MOS transistor to
100 achieve finer adjustments. The block-diagram representation is as

113 The driving strength of the P-MOS/N-MOS transistors impacts the
114 waveform's rise/fall times. Greater driving strength results in
115 shorter rise/fall times. Each P-MOS and N-MOS transistor offers
117 greater driving strength, contributing to achieving the desired
120 The realtek,drive-strength-p is used to control the driving strength
121 of the P-MOS output.
