8 / 190 page RX65N Group, RX651 Group 1. Overview R01DS0276EJ0100 Rev.1.00 Page 8 of 190 Aug 24, 2016 12-bit A/D converter (S12ADFa) 12 bits × 2 units (unit 0: 8 channels; unit 1: 21 channels) 12-bit resolution (switchable between 8, 10, and 12 bits) Conversion time 0.48 μs per channel (for 12-bit conversion) 0.45 μs per channel (for 10-bit conversion) 0.42 μs per channel (for 8-bit conversion) Operating mode Scan mode (single scan mode, continuous scan mode, or 3 group scan mode) Group priority control (only for 3 group scan mode) Sample-and-hold function Common sample-and-hold circuit included In addition, channel-dedicated sample-and-hold function (3 channels: in unit 0 only) included Sampling variable Sampling time can be set up for each channel. Digital comparison Method: Comparison to detect voltages above or below thresholds and window comparison Measurement: Comparison of two results of conversion or comparison of a value in the comparison register and a result of conversion Self-diagnostic function The self-diagnostic function internally generates three analog input voltages (unit 0: VREFL0, VREFH0 × 1/2, VREFH0; unit 1: AVSS1, AVCC1 × 1/2, AVCC1) Double trigger mode (A/D conversion data duplicated) Detection of analog input disconnection Three ways to start A/D conversion Software trigger, timer (MTU3, TMR, TPU) trigger, external trigger Event linking by the ELC 12-bit D/A converter (R12DA) 2 channels 12-bit resolution Output voltage: 0 V to AVCC1 Event linking by the ELC Temperature sensor 1 channel Relative precision: ±1°C The voltage of the temperature is converted into a digital value by the 12-bit A/D converter (unit 1). Safety Memory protection unit (MPU) Protection area: Eight areas (max.) can be specified in the range from 0000 0000h to FFFF FFFFh. Minimum protection unit: 16 bytes Reading from, writing to, and enabling the execution access can be specified for each area. An address exception occurs when the detected access is not in the permitted area. Trusted Memory (TM) Function Protects against the reading of programs from blocks 8 and 9 of the code flash memory Instruction fetching by the CPU is the only form of access to these areas when the TM function is enabled. Register write protection function Protects important registers from being overwritten for in case a program runs out of control. CRC calculator (CRCA) Generation of CRC codes for 8-/32-bit data 8-bit data Selectable from the following three polynomials X8 + X2 + X + 1, X16 + X15 + X2 + 1, X16 + X12 + X5 + 1 32-bit data Selectable from the following two polynomials X32 + X26 + X23 + X22 + X16+ X12 + X11 + X10 + X8+ X7 + X5 + X4 + X2+ X + 1, X32 + X28 + X27 + X26 + X25 + X23 + X22 + X20 + X19 + X18 + X14 + X13 + X11 + X10 + X9 + X8 + X6 + 1 Generation of CRC codes for use with LSB-first or MSB-first communications is selectable Main clock oscillation stop function Main clock oscillation stop detection: Available Table 1.1 Outline of Specifications (7/8) Classification Module/Function Description |
