(Continued)
16-bit I/O timer
16-bit free-run timers 1, 2: 2 channels
Input captures 0, 1 (ICU): Generates an interrupt request by latching a 16-bit free-run timer counter value upon
detection of an edge input to the pin.
Output compares 0, 1 (OCU): Generates an interrupt request and reverses the output level upon detection of a
match between the 16-bit free-run timer counter value and the compare setting
value.
8/16-bit up/down counter/timers 0, 1: 1 channel (8-bit
×
2 channels)
Extended I/O serial interfaces 0, 1: 1 channel
UART (SCI)
With full-duplex double buffer
Clock asynchronized or clock synchronized transmission can be selectively used.
DTP/external interrupt circuit (8 channels)
A module for starting extended intelligent I/O service (EI
2
OS) and generating an external interrupt triggered
by an external input.
Wake-up interrupt
Receives external interrupt requests and generates an interrupt request upon an “L” level input.
Delayed interrupt generation module
Generates an interrupt request for switching tasks.
8/10-bit A/D converter (8 channels)
8/10-bit resolution can be selectively used.
Starting by an external trigger input.
Conversion time: minimum 15.0
μ
s (at machine clock frequency of 16 MHz, including sampling time)
8-bit D/A converter (based on the R-2R system)
8-bit resolution: 2 channels (independent)
Setup time: 12.5

s
Clock timer: 1 channel
LCD controller/driver
A common driver and a segment driver that can directly drive the LCD (liquid crystal display) panel
Clock output function
Note: Do not set external bus mode for the MB90520 series because it cannot be operated in this mode.
