PWMX Enable bit. Setting this bit enables PWMx output. Clearing this bit disables
PWMx output.

MXCR1.x
PWMX+8 Enable bit. Setting this bit enables PWMx output. Clearing this bit disables
PWMx output and activates the I/O pin (see Table 5).
MXCR0 and MXCR1 are read/write registers. Their
value after reset is 00h which corresponds to all PWM
disabled.
PWM will not operate in idle and power down modes
(frozen counter). When idle or power down mode is
entered, the PWM0 to PWM7 output pins are floating
and PWM8 to PWM11 pins are set to general purpose P1
port with the value of P1 SFR.
MXCR0 and MXCR1 are using TSC8051C1 Special
Function Register addresses, E7h and D7h respectively.

PWMCON.0
Counter modulo. Setting this bit sets the modulo to 254. Clearing this bit sets the
modulo to 256.
PWMCON is a write only register. Its value after reset
is 00h which sets the PWM counter modulo to 256.
PWMCON is using TSC8051C1 Special Function
Register address, DFh.
