Options
The following table shows all kinds of options in the microcontroller. All of the OTP options must be defined to ensure a
proper functioning system.
No.
Option
1
PA0~PA7 pull-high resistor enable or disable (by bit)
2
PB0~PB7 pull down resistor enable or disable (by bit)
3
PC0~PC7 pull-high resistor enable or disable (by nibble)
4
PD0~PD7 pull-high resistor enable or disable (by nibble)
5
PE0~PE5 pull-high resistor enable or disable (by nibble)
6
LVR enable or disable
PWM selection: (7+1) or (6+2) mode
7
PD0: level output or PWM0 output
PD1: level output or PWM1 output
8
SIO (Serial Interface) enable/disable (if SIO is enabled then PE0~PE3 I/O port will be disabled)
9
SIO_ CPOL: Clock polarity 1/0: clock polarity rising or falling edge
10 SIO_WCOL: Enable/disable
11 SIO_CSEN: Enable/disable, CSEN mask option is used to enable/disable (1/0) software CSEN function
12 WDT enable/disable
13 WDT clock source: f_SYS/4 or WDTOSC
14
WDT timeout period: 2¹²/f_S~2¹³/f_S, 2¹³/f_S~2¹⁴/f_S, 2¹⁴/f_S~2¹⁵/f_S, 2¹⁵/f_S~2¹⁶/f_S
15 ²CLRWDT² instruction (s): 1 or 2
16 PA0~PA7 wake-up enable/disable (by bit)
17* EP1~EP3 Data pipe enable: EP1, EP2, EP3 enable/disable. (Default is enable)
Note: *: The purpose of this option is to enable the endpoint that will be used, and disable the endpoint that will not be
used.
