HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM Reset and Initialisation A reset function is a fundamental part of any microcontroller ensuring that the device can be set to some predetermined condition irrespective of outside parameters. The most important reset condition is after power is first applied to the microcontroller.
Page 99 HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM RES Pin Reset As the reset pin is shared with I/O pins, the reset function must be selected using a control register, RSTC. Although the microcontroller has an internal RC reset function, if the VDD power supply rise time is not fast enough or does not stabilise quickly at power-on, the internal reset function may be incapable of providing proper reset operation.
Page 100 HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM There is an internal reset control register, RSTC, which is used to select the external RES pin function and provide a reset when the device operates abnormally due to the environmental noise interference.

HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM Timer Modules – TM One of the most fundamental functions in any microcontroller devices is the ability to control and measure time. To implement time related functions the device includes several Timer Modules, generally abbreviated to the name TM.
Page 134: Tm Interrupts
TM output function must first be setup using relevant pin-shared function selection register. Note that there is no relevant input function selection register, IFSn, to select the input signal source for the PTCK4~PTCK7 and PTP4I~PTP7I pins in the HT67F2350 device.

HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM Programming Considerations The TM Counter Registers and the Capture/Compare CCRA and CCRP registers, all have a low and high byte structure. The high bytes can be directly accessed, but as the low bytes can only be accessed via an internal 8-bit buffer, reading or writing to these register pairs must be carried out in a specific way.

HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM Data, Parity and Stop Bit Selection The format of the data to be transferred is composed of various factors such as data bit length, parity on/off, parity type, address bits and the number of stop bits. These factors are determined by the setup of various bits within the UnCR1 register.
Page 213 HT67F2350/HT67F2360 HT67F2370/HT67F2390 Advanced A/D Flash MCU with LCD & EEPROM Transmitting Data When the UARTn is transmitting data, the data is shifted on the TXn pin from the shift register, with the least significant bit LSB first. In the transmit mode, the TXR_RXRn register forms a buffer between the internal bus and the transmitter shift register.
