3.3 Ethernet.1: Setting up the Ethernet interface in RMII mode
Introduction:
The LPC2366 has an Ethernet interface, which can be interfaced with an off-chip PHY
using the RMII interface.
Problem:
The default configuration of the device does not enable the RMII interface.
Work-around:
To use the Ethernet interface in RMII mode write a 1 to bit 12 (P1.16) in PINSEL2 register
(located at 0xE002 C008). This workaround only applies for Rev ‘-’ devices and does not
apply for Rev ‘A’ and newer devices. In order to have both Rev ‘-’ and other revisions
coexist in the same piece of software, the MAC module ID can be used to identify the part
and determine if port pin P1.6 needs to be set or not.
Here are the steps (along with some sample code) to initialize the MAC based on the
module ID:
1. In master header file lLPC24xx.h, make sure Module ID is defined (Please note, this
ID register is not documented in the User's Manual).
#define MAC_BASE_ADDR
#define MAC_MODULEID (*(volatile unsigned long *)(MAC_BASE_ADDR + 0xFFC)) /*
Module ID reg (RO) */
0xFFE00000
2. In the beginning of the MAC initialization file, add below definition:
#define OLD_EMAC_MODULE_ID
0x3902 << 16) | 0x2000)
3. In MAC initialization routine, right after setting the EMAC clock in the PCONP register,
add a few lines as below:
/* Turn on the ethernet MAC clock in PCONP, bit 30 */
regVal = PCONP;
regVal |= PCONP_EMAC_CLOCK;
PCONP = regVal;
/*------------------------------------------------------
* Write to PINSEL2/3 to select the PHY functions on P1[17:0]
* P1.6, ENET-TX_CLK, has to be set for Rev '-' devices and it
* must not be set for Rev 'A’ and newer devices
*------------------------------------------------------*/
regVal = MAC_MODULEID;
if ( regVal == OLD_EMAC_MODULE_ID )
{
/* On Rev. '-', MAC_MODULEID should be equal to
OLD_EMAC_MODULE_ID, P1.6 should be set. */
PINSEL2 = 0x50151105;
/* selects P1[0,1,4,6,8,9,10,14,15] */
}
else
{
/* on rev. 'A', MAC_MODULEID should not equal to
