Refer to “ (2) Source Clock/Machine Clock” for tMCLK.
m is CS4 bit and CS3 bit (bit 4 and bit 3) of clock control register (ICCR0) .
n is CS2 bit to CS0 bit (bit 2 to bit 0) of clock control register (ICCR0) .
Actual timing of I2C is determined by m and n values set by the machine clock (tMCLK) and CS4 to CS0 of
ICCR0 register.
Standard-mode :
m and n can be set at the range : 0.9 MHz < tMCLK (machine clock) < 10 MHz.
Setting of m and n limits the machine clock that can be used below.
(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
≤ 10 MHz
Fast-mode :
m and n can be set at the range : 3.3 MHz < tMCLK (machine clock) < 10 MHz.
Setting of m and n limits the machine clock that can be used below.
(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
