I 2 C? service for three slave devices:
0xA2: Real-Time Clock (RTC)
0xA8: EEPROM
0xAA: Executive (EXEC)
LED management, set/reset LEDs per state register
Initialization, Idle loop and Interrupt Service Routine context
management
Monitor PICkit Serial Analyzer interface I/O pins – post results to state
register
I 2 C? device: real-time clock emulation maintains 16 locations for
register-based I/O
Utilizes TMR0 as a source for multiple “soft” timers
Utilizes TMR1 with external 32 kHz crystal for RTC 1-second ‘ticks’

Supervisory features
All devices (slave addresses) respond to the I 2 C protocols described below. Each slave
device supports a fixed number of word addresses (see section B.6 Slave Devices
below). The word address is automatically incremented during a transaction for
sequential access of the device registers. If the word address is incremented beyond
the end of the supported address range, the address will “wrap”.

Write Byte(s) – This transaction is used to write one or more bytes. The maximum
number of bytes is slave-dependant.
