Description
Causes VPULSE to be output on DIO1.
Causes WPULSE to be output on DIO0.
Causes XPULSE to be output on DIO6.
Causes YPULSE to be output on DIO7.
Serial EEPROM interface data.
Serial EEPROM interface control.
Specifies the power equation.
Interrupt enable bits. These bits enable the XFER_BUSY, the RTC_1SEC, etc. The
bits are set by hardware and cannot be set by writing a 1. The bits are reset by writing
0. Note that if one of these interrupts is to enabled, its corresponding 8051 EX enable
bit must also be set. See
EQU[2:0]
Note:
*The available CE codes implements only equation 5. Contact your local Teridian representative to
obtain CE code for equations 3 and 4.
