Pulse Width Modulators

Table 53 IR Capture Register 1 04h: Bank C (IR_CP1)
The Z90255 has 11 Pulse Width Modulator channels. PWM1 through PWM10 have
6-bit resolution and are typically used for audio and video level control. PWM11 has
14-bit resolution and is typically used for voltage synthesis tuning. PWM11 uses
two registers to accommodate its 14-bit resolution. PWM6 can be configured as
either 14-bit or 6-bit.
PWM Mode Register
PWM Mode Register (Table 54) controls the setting of multiplexed pins 1-7. These
pins can be configured to function as PWM output ports or regular output ports. If
a bit is reset to 0, the pin outputs the PWM signal. If a bit is set to 1, the pin is a
regular output port.
