Description
I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT. To apply
external clock, input the clock from XIN and leave XOUT open
I/O pins for a sub clock oscillation circuit. Connect a crystal
oscillator between XCIN and XCOUT. To apply external clock,
input the clock from XCIN and leave XCOUT open
Outputs BCLK signal
Outputs clock having thesame frequency as fC, f8, or f32

Input pins for the timer A0 to A4
Input pins for the timer B0 to B5
output pins for the three-phase motor control timer
Input pins for data transmission control
Output pins for data reception control
Inputs and outputs the transfer clock
Inputs serial data
Outputs serial data (TxD2 is a pin for the N-channel open drain
output.)
Inputs and outputs serial data (SDA2 is a pin for for the N-
channel open drain output.)
Inputs and outputs the transfer clock (SCL2 is a pin for the N-
channel open drain output.)
Outputs serial data when slave mode is selected (SDA2 is a pin
for the N-channel open drain output.)
Inputs serial data when slave mode is selected
Input pins to control serial I/O special function
