Bit 4 (T1EN): TMR1 enable bit
"0" : TMR1 is off (default value)
"1" : TMR1 is on
Bit 5 (T2EN): TMR2 enable bit
"0" : TMR2 is off (default value)
"1" : TMR2 is on
Bit 6 (PWM1E): PWM1 enable bit
"0" : PWM1 is off (default value), and the corresponding pin carries out
the PC1 function
"1" : PWM1 is on, and the corresponding pin will be automatically set
as output pin
Bit 7 (PWM2E): PWM2 enable bit
"0" : PWM2 is off (default value), and the corresponding pin carries out
the PC2 function
"1" : PWM2 is on, and the corresponding pin will be automatically set
as output pin

Bit 0 ~ Bit 1 (P60 ~ P61): Ports 60 ~ 61 are used in IRC and ERIC mode. In these
modes, Ports 60 ~ 61 are defined as general purpose IO. In Crystal mode,
Ports 60 ~ 61 are defined as crystal input (XIN and XOUT) pins.
Bit 2 ~ Bit 6 (P62 ~ P65): 4-bit Port 6 I/O data register. The IOC register can be used
to set each bit either as input or output.
Bit 6 ~ Bit 7 (undefined): These bits are not used

A specified value keeps the output of PWM1 to remain at high until such value matches
the value of TMR1.
