*1 : R, C : Pull-up resistance and load capacitance of the SCL and SDA lines.
*2 :
Refer to “ (2) Source Clock/Machine Clock” for details on tMCLK.
m is the CS4 and CS3 bits (bit 4 and bit 3) of the I2C clock control register (ICCR0) .
n is the CS2 to CS0 bits (bit 2 to bit0) of the I2C clock control register (ICCR0) .
The actual I2C timing is determined by the machine (tMCLK) and the values of m and n configured in bits
CS4 to CS0 of the I2C clock control register (ICCR0) .
Standard-mode :
m and n can be set in the range : 0.9 MHz < tMCLK (machine clock) < 10 MHz.
The machine clock to be used is determined by the settings of m and n as follows.
(m, n)
= (1, 8)
: 0.9 MHz < tMCLK
≤ 1 MHz
(m, n)
= (1, 22) , (5, 4) , (6, 4) , (7, 4) , (8, 4)
: 0.9 MHz < tMCLK
≤ 2 MHz
(m, n)
= (1, 38) , (5, 8) , (6, 8) , (7, 8) , (8, 8)
: 0.9 MHz < tMCLK
≤ 4 MHz
(m, n)
= (1, 98)
: 0.9 MHz < tMCLK
≤ 1 MHz
Fast-mode :
m and n can be set in the range : 3.3 MHz < tMCLK (machine clock) < 10 MHz.
The machine clock to be used is determined by the settings of m and n as follows.
(m, n)
= (1, 8)
: 3.3 MHz < tMCLK
≤ 4 MHz
(m, n)
= (1, 22) , (5, 4)
: 3.3 MHz < tMCLK
≤ 8 MHz
(m, n)
= (6, 4)
: 3.3 MHz < tMCLK
≤ 10 MHz
