(256 –(reload value Timer1))
Reload value Timer 1 in Mode 2.
NOTES:
1. These frequencies exceed the upper limit of 100kHz of the I
2
C-bus specification and cannot be used in an I
2
C-bus application.
2. At f
osc
= 24 MHz/30 MHz the maximum I
2
C-bus rate of 100kHz cannot be realized due to the fixed divider rates.

NOTES:
1. These bit rates are for “fast-mode” I
2
C-bus applications and cannot be used for bit rates up to 100 kbit/sec.
2. Serial status register S1STA is a read only register.
